You might find that the US are unwilling to sell F-22 because it it that airframe that will take on the Iranian and Nth Korean IADS at once (seem to remember their 2 war simultaneous theory). Before anyone jumps up and down, I really mean that it will be used on day 2 after all the CALCMs, TLAMs, Black UCAVs etc have done the dirty work, and the planned 'swift' clean up commences. The US may want to do this sweep on its own, as it would be difficult to sell such a war to the UN et al, given the attempts to gain international support to clean out Iraq during the spring offensive of '03. Therefore, why should it sell its nice new toys, only to have some of them denied the use that they were intended.
