Until recently, most politicians, pundits and others among the so-called “smart people” insisted that Election 2012 was all about jobs, jobs, jobs. The more broad-minded contended that the related issues of the lousy economy and the imperatives of deficit reduction might also feature. But that was all the mattered, especially in the presidential contest.

Then, GOP candidate Herman Cain – a successful businessman who has risen in the polls in no small measure on the strength of his claim to have actually created jobs – gave an interview in which he seemed unaware that Communist China has the bomb.

Without skipping a beat, the elites denounced him as unfit to serve on the grounds that a man who was not proficient in national security and foreign policy matters could never become president. The jobs-jobs-jobs leitmotif gave way, at least for a time, to a new theme: the White House is no place for on-the-job-training about the nation’s defense.

How quickly they forget. What Barack Obama knew about U.S. security policy before he became president amounted to little more than the anti-colonialist sentiments of his father and the virulently anti-American agitation of PLO flak Rashid Khalidi, terrorist William Ayers, revolutionary Saul Alinsky and radical pastor Jeremiah Wright.

Unfortunately, despite the on-the-job foreign and defense policy training Mr. Obama has, in fact, received during his time in office over the past nearly three years, he still seems largely clueless about U.S. security interests – and what it takes to safeguard them. Consider the following sample of his myriad, unforced errors:

The associated damage is likely to be compounded by further reductions at the hands of the congressional supercommittee or, failing acceptance of its recommendations by the full Congress, via a meat-ax known as “sequestration.” The latter would impose a further roughly $600 billion across-the-board reduction in Pentagon spending. The Obama administration’s own civilian and uniformed defense leaders have warned that the effects of such a one-two punch would be catastrophic.

Should expertise on national security and foreign policy be a prerequisite for the presidency? The answer obviously must be a resounding “Yes” – especially in a world as dangerous as ours. Have we had it over the past nearly three years? The answer is equally resoundingly, “No.”

We have to insist on a level of competence in the defense and foreign policy portfolio of our elected national leaders. In that connection, it is heartening that twoof the upcoming debates between Republican presidential candidates – one on November 12th at Wofford College in South Carolina and one sponsored by the American Enterprise Institute, the Heritage Foundation and CNN in Washington on November 22nd – will focus on national security-related topics.

While the liquidations of Osama bin Laden, Anwar al-Awlaki and a number of other high-profile terrorists on President Obama’s watch are welcome, those accomplishments are, regrettably, more than offset by his serious failings like those noted above. The American people deserve, and need, a competent Commander-in-Chief. And they had better insist on getting one.
