Could Israel go it alone in Iran?

The latest annual report of an Israel think tank says that, yes, Israel is capable of knocking out Iran's nuclear capability on its own.

Time is working in Iran's favor, and barring military action, Iran's possession of nuclear weapons is only a matter of time," the institute said in a statement distributed at a news conference where it released its annual assessment of the Middle East's strategic balance.

The report punts, however, on the vital question of whether Israel should launch military strikes.

Of course, any Israeli attack on Iranian nuclear facilities would require U.S. approval, especially given that the United States controls Iraqi airspace.
