We don't have AIM-120 A2A. Israel blocked the sale.
Nope. The US is trying to sell the PAC-3 to Egypt and they are very enthusiastic about it. I'd say it because they don't want Egypt to buy the S-300/400 which Israel already said was one of it's concerns. If we switch to Russian arms (very hard to do, as stated by contedicavour) by 2009 we might buy the Growler (unlikely ,but with recent events ,maybe).
It's definitely true that Egypt could switch to "all Russian made systems." But, as it was pointed out earlier, it would be a nightmare to switch: logistically and operationally. Just a quick note, the US and others in the west probably won't sell Egypt new (or advanced) weapons. The basic reason is (I think you mentioned it earlier--Iran trying to win Egypt's support... which many have said has alredy happened), the US is not convinced that there is any real stability in Egypt today. If Mubarak were 50yrs/old, I don't think there would be a problem. However, Mubarak in Egypt, just like Abdullah in SA, are older and the US sees the "infighting" for, "The Day After." The US is pretty much clueless as to who will take over, while Mubarak wants his Son to take over, the US is far from convinced that this is what will happen. If Egypt loses a moderate leader and a "radical" places himself in power, the US does not want it's weapons in the hands of "radicals."
IMO, this is the reason that both the Saudis and Egypt are not getting usual treatment today. An interesting note is that Prince Bandar just put his house in Aspen CO. up for sale for $150,000,000 (it's worth far more, but he "wanted to keep the price low, to make sure people didn't think he was living too extravagantly"
). I don't think he needs the money, but I have a feeling he won't be spending a great deal of time in the US anymore.
The other thing with Egypt is, the US can basically turn all systems off on American-Egyptian Military systems. Egypt would have to spend a fortune to build it's military again, to today's specs. The threat of the US/West not selling weapons to Egypt, is actually more of a statement to any who might want to follow Mubarak. There's a subtle message that if his son does not replace Mubarak, any radical gov't will be treated like "Hamas."
Congress cutting off some money to Egypt isn't a big deal, it's more of a political statement/message. If all mentioned above is cleared up, the US will add the money withheld or give Egypt a "credit."
As for basing, google "US military bases in Egypt," if there is a problem with "getting returns for this," just ask, and i'll do it (post it here) as soon as I get a chance.
Peace
