DEBKAfile thinks that the USA is behind the Egyptian revolt. See their article here. What motive could the USA possibly have to overthrow a staunch ally? Well, a couple of things come to mind…
You probably remember Vice President Biden’s visit to Israel in March 2010. It sticks in the memory because many people considered it a huge insult to Biden when the Israelis announced construction plans for a new settlement in East Jerusalem. I have no idea if the Israelis did that on purpose, but if Obama felt slighted, you could expect him to eventually deliver some sort of payback. And the collapse of the status quo in Egypt is not likely to improve Israel’s security.
The other thing that comes to mind is American commanders saying that Israel was making the War in Afghanistan more difficult. The theory is that if Israel treats the Palestinians badly, more terrorists are motivated to attack US troops. I have no idea if that is actually true or not, but both Generals McChrystal and Petraeus publicly criticized Israel on the point.
So, there is a certain logic to the Obama Administration fomenting rebellion in Egypt. It delivers payback to the Israelis, makes Obama a hero to the Arabs, which helps the president wrap up the Iraq and Afghanistan wars in time for the 2012 election.
If DEBKAfile is right, then we might be witnessing an historic sea-change in US-Israeli relations. This might also explain why Obama did not accommodate the Israeli/Saudi desire for an attack on Iran’s nuclear facilities.
