Another major wave of U.S. troops sent to Afghanistan. A Detroit-bound airliner imperiled by a terrorist on Christmas Day. A stunning blow to CIA operations targeting the Taliban and al Qaeda. A surge of political attacks against President Obama led by an aggressively partisan former vice president.

In recent weeks America’s current era of war has escalated to a next level. Obama didn’t preside over its inception, of course, but it is ever his to handle. Although the nation’s economic reckoning is far from over, what happens on the national security front is probably more likely to define Obama’s presidency than anything else.

His speech Thursday night addressing the U.S. intelligence debacle at Christmas reflected this. In his closing remarks, Obama made a point of disarming recent partisan attacks; although he didn’t name Dick Cheney specifically, some of his comments clearly were a retort to the former vice president’s assertion that Obama doesn’t take the terrorist threat seriously:

Over the past two weeks, we’ve been reminded again of the challenge we face in protecting our country against a foe that is bent on our destruction. And while passions and politics can often obscure the hard work before us, let’s be clear about what this moment demands. We are at war. We are at war against al Qaeda, a far-reaching network of violence and hatred that attacked us on 9/11, that killed nearly 3,000 innocent people, and that is plotting to strike us again. And we will do whatever it takes to defeat them.

In the New York Post, Rich Lowry beamed that Obama’s rhetoric could’ve been written by Dick Cheney himself.

Most striking was the president’s reiteration of the principles by which he will prosecute America’s long war:

Here at home, we will strengthen our defenses, but we will not succumb to a siege mentality that sacrifices the open society and liberties and values that we cherish as Americans, because great and proud nations don’t hunker down and hide behind walls of suspicion and mistrust. That is exactly what our adversaries want, and so long as I am President, we will never hand them that victory. We will define the character of our country, not some band of small men intent on killing innocent men, women and children. And in this cause, every one of us — every American, every elected official — can do our part.

On MSNBC Thursday night, veteran Washington columnist Howard Fineman pointed out how anxious George W. Bush had been to get through his final weeks in office without another terrorist attack taking place inside the U.S. Apparently Bush was plenty eager to get out of town with what he viewed as a clean post-9/11 record.

The equation Obama faces is not a matter of if, but when. American society would do well to accept that reality, as even David Brooks has now said. Fortunately, the current commander in chief appears driven to move ahead with a markedly different approach than his predecessor. “Instead of giving into cynicism and division, let’s move forward with the confidence and optimism and unity that defines us as a people,” Obama concluded on Thursday. “For now is not a time for partisanship, it’s a time for citizenship — a time to come together and work together with the seriousness of purpose that our national security demands. That’s what it means to be strong in the face of violent extremism. That’s how we will prevail in this fight.”
