North American Aviation boycotted Israel in the 1950s, via refusing to sell them the most advanced fighter plane at the time: the F-86 Sabre. Israel then had to come crawling back to it's former colonial masters for our Gloster Meteors for it's fledgling air force (even Supermarine Spitfires befire then).
Obama potentially doing the same, re. F-22s? F-35s: the culmination of the JSF; with US-Israeli relations - i.e. Ben NetanYahoo - being at an all-time low, and the whole 'Two-State' policy, re, Israel & Palestine, I guess 'JSF' will also mean 'Jordan-Shared Fighter'.
Jordan: very much US-allied. Very much anti-ISIS. You're gonna need all the non-boycotting allies you can get, with the current enemy going to war with Christianity in your country, so frankly people voting with their wallets against a few bakers in the US is rather a low priority I'd say, eh Timmy Pukeman?
F-35s. We Brits are in line to buy those, for our new Queen Elizabeth-class carrier: 2/3rds the size of the Nimitz-class. The 'Special Relationship', and all that jazz. No 5th Gen plane for you, Israel! [/Hardware Nazi]
...still, Israel could always buy for the air wing of their IDF Eurofighter Typhoons: British. >:D

@Glandu
True, but I was referencing how Israel were reduced to buying in the 1950s, the Gloster Meteor. Thus having to do the same, in the 21st Century.
