Drudge links to a Times Online article which reveals that Saudi Arabia has given the Israelis permission to transit their air space to launch an attack on Iran's nuclear weapons facilities. It's in the Saudis' interests to have these facilities destroyed and since President Obama doesn't seem too resolved to do much to prevent the proliferation of nuclear weapons in the region, the Saudis are apparently content to let Israel do it.
The Obama administration, if Vice-president Biden can be relied upon to have been speaking for the president, seems to have given Israel a green light to do what it is loath to do itself.
Perhaps the Israelis will hold off for a while, however, since the instability in Tehran may yet cause that regime to topple and be replaced with one that'll have a more sensible position on nukes. But if it appears after three or four weeks that the regime is simply consolidating its power, the Israelis will probably feel they are being left with no choice but to launch a strike, or series of strikes, to destroy Iran's ability to produce weapons of mass destruction.
