James Buchanan's presidency was a catastrophe for America. He refused from the outset to face the slavery crisis, declaring in his inaugural address of 1857 that the barbarous institution was "of no practical importance."

Buchanan did nothing even after Abraham Lincoln's House Divided speech in 1858 warning that "a house divided against itself cannot stand." The secession crisis followed, then the Civil War.

A century and a half later, as President Obama heads to Texas, his presidency may be at risk of failing in a manner that disturbingly recalls the blind ineptitude of Buchanan.

Obama's Katrina on the border

Protecting the border is the first mark of national sovereignty and a president's most basic duty. With a swelling flood of Central American kids crossing the U.S. border from Mexico into Texas for the past year and more, President Obama seems capable only of talking.

He's going to Texas this week, to be sure, but to speak at four Democratic fundraisers. A last-minute talkathon with local officials will be as close to addressing the border crisis as Obama will get in the Lone Star State. He might as well be gazing down at the border crisis from Air Force One.

That means Obama's 2012 campaign vow that the border was secure is no longer true, if it ever was, because U.S. Border Patrol agents are overwhelmed and the flood continues. Obama requests $3.7 billion, mostly to care for those who have already crossed the border, not to prevent more from doing so.

Catastrophic failure number two

Intrinsically linked to the first, the second most fundamental obligation of the president is to protect the nation against attacks by America's enemies.

Whether it's Russia's Vladimir Putin thumbing his nose at Obama in the Ukraine, Ayatollah Ali Khamenei blowing up Obama's nuclear deal with Iran or the Chinese military's growing confidence they can defeat the U.S., America's enemies are everywhere on the move. And al Qaeda is stronger now than at any time since 9/11, even as Obama closes Gitmo and sends terrorists to civilian courts, as if they were burglars or muggers.

These things happen even as Obama shrinks U.S. military power as has not been seen since the end of World War II. Army divisions are being dismissed, critical aging weapons aren't being updated or replaced with more advanced versions, ships and aircraft are being retired and pay and benefits are being slashed.

Catastrophic failure number three

A vibrant, growing economy is as essential to American security as a muscular military. But nearly six years into Obama's recovery, the U.S. economy is stagnant, if not shrinking.

Millions of Americans who want to work have given up looking for jobs and recent college graduates face the worst employment prospects in generations. Having a job in 2014 too often means doing part-time work for low wages.

Perhaps worst of all, middle class Americans fear their children won't have it as good as they did. With a $17 trillion national debt that will have to be repaid sooner or later, they are all too likely to be right to be fearful.

And it's going to get worse for years to come, thanks to the explosion of federal intervention under Obama. Whole industries are under attack and small businesses -- the heart of U.S. job creation -- are staggering under the dead hand of regulation, especially with Obamacare.

So what's left?

Buchanan left office just before the catastrophe of the Civil War he did nothing to prevent fell upon the nation. The estimated 625,000 men killed in action made it the most costly conflict, per capita, in American history.

As with Buchanan, Obama will likely be out of office when the most serious consequences of his tenure are felt. Enemies like Iran's Ayatollahs, however, may opt to strike now while the U.S. has a leadership crisis.

More than two-thirds of Americans believe the country is on the wrong track. Without an abrupt reversal by Obama of the defining policies of his time as chief executive, the next big question is whether Obama will leave them with sufficient time and resources to get things back on the right track.
