That's the question Powerline posed today, prompting a flood of e-mails and links from readers. Actually, we answered that question in some detail a few months ago. While Israel has more than enough F-16Is and F-15Is to mount a strike against targets in Iran, the real limiting factor is the number of KC-707 tanker aircraft in its inventory. The KC-707s are necessary to provide pre and post-strike aerial refueling for the fighters. By most estimates, Israel has only 5-7 KC-707s in the IAF inventory, enough to support the type of strike we described.
Additionally, Israel has an unknown number of Jericho II medium-range missiles. However, the missiles lack the accuracy that Tel Aviv would likely desire in an initial strike against Iran. But, in responding to an Iranian missile attack (using WMD), the Jerichos are more than sufficient to strike area targets, including Iran's population centers.
