Mitt Romney has nothing really coherent or substantive to say about domestic policy, but at least he can sound energetic and confident about it. On foreign policy, the subject of Monday night’s final presidential debate, he had little coherent to say and often sounded completely lost. That’s because he has no original ideas of substance on most world issues, including Syria, Iran and Afghanistan.

During the debate, on issue after issue, Mr. Romney sounded as if he had read the boldfaced headings in a briefing book — or a freshman global history textbook — and had not gone much further than that. Twice during the first half-hour, he mentioned that Al Qaeda-affiliated groups were active in northern Mali. Was that in the morning’s briefing book?…

Mr. Romney’s closing statement summed it all up. He said almost nothing about foreign policy. He moved back to his comfort zone: cheerfully delivered disinformation about domestic policy.
