WASHINGTON -- With one eye on a sudden crisis with Iran, President Barack Obama on Tuesday urged Americans in his final State of the Union address to reject the politics of tribalism and fear that have rocked the campaign to find his successor and to come together to build a nation that was "clear-eyed, big-hearted" and "optimistic."
Delivering his annual report to the nation, Obama did not name Republican 2016 candidates, but took clear, implied shots at them nevertheless, including front-runner Donald Trump and Sens. Marco Rubio and Ted Cruz, as he sought to shape the 2016 electoral battlefield for his Democrats and argued that America's destiny was in doubt because of a political system festering in malice, gridlock and in the grip of the rich and the powerful.
Obama also took aim at critics who accuse him of weakening American power abroad and Republicans who say he is underplaying the threat from radical Islamist groups such as ISIS. He mocked the contention that fighters on "on the back of pickup trucks and twisted souls plotting in apartments or garages" represented an existential threat to America.
The President acknowledged that a torrent of change, technological advances and economic dislocation had left many Americans fearful of the future and anxious as social structures that have underpinned the life of the nation for decades fray. But he urged them not to fall prey to the a periodic temptation that has emerged throughout history to alienate minorities and resist social change.
"Each time, there have been those who told us to fear the future; who claimed we could slam the brakes on change, promising to restore past glory if we just got some group or idea that was threatening America under control," Obama said. "And each time, we overcame those fears."
"We made change work for us, always extending America's promise outward, to the next frontier, to more and more people. And because we did -- because we saw opportunity where others saw only peril -- we emerged stronger and better than before."
Economic opportunity, security and a sustainable, peaceful planet are possible, he said, if the country could return to "rational, constructive debates."
"It will only happen if we fix our politics," he said.
While Obama avoided the long list of legislative proposals that Congress has no intention of taking up, he strongly defended his domestic record, claiming credit for 14 million new jobs and a halving of the unemployment rate. He said those who claimed the economy was in decline are "peddling fiction."
He rebuked politicians who draw congressional districts to protect safe seats and vowed to launch a national effort to secure voting rights, an issue particularly important to minority communities. And he named Vice President Joe Biden, who lost his beloved son Beau to cancer last year, to head "Mission Control" in a new "moon shot" to cure the disease. He told conservatives who deny climate change to "have at it" because they were defying the world.
Iran crisis in the background
The President pressed ahead with the address despite a fast moving diplomatic crisis with Iran that erupted when the Islamic Republic's Revolutionary Guard Corps seized 10 U.S. sailors in the Persian Gulf after they apparently strayed into Iranian territorial waters.
After several hours of frenzied diplomacy, Secretary of State John Kerry told CNN that the service members would be released "very soon," while senior administration officials said that the President would not address the issue in his speech -- though he would defend the legacy-building deal reached to halt Iran's nuclear program.
In a way, Obama's final State of the Union address was a microcosm of his entire presidency: involving a chorus of hope and optimism about America's destiny and the transformative nature of change, undercut by the poisoned political divides he has been unable to narrow, and fierce opposition from Republicans who believe he has transformed the nation in a way that waters down its exceptional qualities and thwarted the Constitution.
Meanwhile, a foreign policy crisis raging in the Middle East underscored the struggles Obama has had to impose U.S. authority on an increasingly chaotic world that has challenged his core mission of ending costly American wars abroad.
Obama's rebuttal to campaign trail rhetoric
The first African-American president also offered a detailed rebuttal of the kind of politics that alienates people rather than unites them. It seemed clear that he had Trump in his thoughts.
"As frustration grows, there will be voices urging us to fall back into tribes, to scapegoat fellow citizens who don't look like us, or pray like us, or vote like we do, or share the same background," Obama said, voicing a familiar critique of Democrats and some Republicans at the rhetoric of the billionaire real estate mogul whose populist campaign has taken American politics by storm.
"We can't afford to go down that path. It won't deliver the economy we want, or the security we want, but most of all, it contradicts everything that makes us the envy of the world."
Obama appeared to relish the chance to take on Republican critics who have lambasted his performance as commander in chief.
"I told you earlier all the talk of America's economic decline is political hot air. Well, so is all the rhetoric you hear about our enemies getting stronger and America getting weaker. The United States of America is the most powerful nation on Earth. Period. It's not even close," Obama said.
The man who burst on the political scene by rejecting the notion that there was a red America or a blue America, also diagnosed a sick political system.
"It doesn't work if we think the people who disagree with us are all motivated by malice, or that our political opponents are unpatriotic.," Obama warned, and even accepted a share of the blame for not uniting warring political factions.
"It's one of the few regrets of my presidency -- that the rancor and suspicion between the parties has gotten worse instead of better. There's no doubt a president with the gifts of Lincoln or Roosevelt might have better bridged the divide, and I guarantee I'll keep trying to be better so long as I hold this office.
After weeks of intense campaigning, Obama was not expected to make gun control a centerpiece of his speech. But he did leave a seat open in the first lady's guest box, in a stark reminder of silenced victims of gun violence.
Warns on ISIS
And he unloaded on Republicans who have responded to the spread of ISIS across much of the Middle East and the group's apparent widening of its target list to Europe and the United States, by warning that its rise is a threat to America itself.
"As we focus on destroying ISIL, over-the-top claims that this is World War III just play into their hands," Obama said.
"They do not threaten our national existence. That's the story ISIL wants to tell; that's the kind of propaganda they use to recruit," Obama said, warning against pushing away vital Americans allies in the Middle East by "echoing the lie" that the group represents Islam.
"We just need to call them what they are --- killers and fanatics who have to be rooted out, hunted down, and destroyed," he said, warning that "tough talk or calls to carpet bomb civilians" may work as a soundbite but don't pass muster on the world stage. Obama's comments appeared aimed at Cruz, who has warned he would carpet bomb ISIS and Rubio, who says America is waging an existential fight against radical Islamic terrorism.
Republicans pounce on Iran timing
The Iran incident complicated Obama's effort to counter claims by critics that the escalating chaos in the Middle East is the result of a deficit of U.S. leadership and emboldened Republican attacks by presidential candidates who contend his "weak" performance as commander-in-chief has opened vacuums exploited by U.S. enemies.
Republican presidential candidates and lawmakers immediately seized on the incident to charge that Obama has emboldened Iran's aggressive behavior in its neighborhood by offering sanctions relief in return for a halting of its nuclear weapons program.
"This is the latest manifestation of the weakness of Barack Obama, that every bad actor... views Obama as a laughingstock," Cruz said on WRKO radio.
Rubio said Iran's provocations were the result of having a "weak president" in the Oval Office. "Iran is testing the boundaries of this administration's resolve. And they know the boundaries are pretty wide and this administration is willing to let them get away with many things," said Rubio on Fox News.
And Colorado Republican Sen. Cory Gardner told CNN's Jake Tapper on "The Lead" that Obama should delay the start of his speech "to talk about what has happened."
Carson decries anticipated 'rosy' picture
Republicans agree with Obama that his presidency has been transformational -- but in a bad way. They believe he has presided over anemic growth rates, wielded executive power on immigration, gun control and climate change to thwart the Constitution, is oblivious to the severity of Islamist terrorism and has engineered an era of declining American power in the world.
"At the State of the Union address tonight we're going to be given a very rosy picture of what's going on," Republican presidential candidate Ben Carson told CNN. "And the fact of the matter is, you know, America is now at great risk. Our adversaries no longer fear us, our allies don't trust us. We have to really bring our strength back."
The GOP will highlight one of its rising stars, South Carolina Gov. Nikki Haley, who often is touted as a possible vice presidential nominee, in its official televised response to the President's address.
Haley will paint an unflattering picture of Obama's America and say the nation would soon have a chance to turn the page.
"The President's record has often fallen far short of his soaring words," Haley said in excerpts of her remarks released by House Speaker Paul Ryan's office. "Many Americans are still feeling the squeeze of an economy too weak to raise income levels. We're feeling a crushing national debt, a health care plan that has made insurance less affordable and doctors less available, and chaotic unrest in many of our cities. Even worse, we are facing the most dangerous terrorist threat our nation has seen since September 11th, and this president appears either unwilling or unable to deal with it."
Haley took a shot at Obama's foreign policy record, saying a Republican president would "make international agreements that were celebrated in Israel and protested in Iran, not the other way around."
Haley decries 'siren call of the angriest voices'
The governor will also highlight her personal story as a daughter of Indian immigrants and draw a contrast with some of the rhetoric currently on display in the primary campaign.
"Today, we live in a time of threats like few others in recent memory," she will say. "During anxious times, it can be tempting to follow the siren call of the angriest voices. We must resist that temptation. No one who is willing to work hard, abide by our laws, and love our traditions should ever feel unwelcome in this country."
Tuesday's address before a packed House chamber also marked the debut of Ryan -- a longtime Obama rival -- on the platform alongside Biden.
And as per tradition, one Cabinet member did not attend the speech. Department of Homeland Security Secretary Jeh Johnson has been named as the "designated survivor."
