I disagree with the Israelis not *wanting* the F-22.They are pretty self-sufficient as it stands now. It is widely discussed within the F-16 community that every airplane LM delivers to the IAF gets almost totally disassembled, and reassembled with significant changes made.
However, as it stands now we are claiming we aren't selling the F-22 to any foreign militaries (let me go laugh for a second). When that changes the Israelis will likely come up with the money. The Japanese will likely want to jump in as well.
A few Arab states are likely to show up with their checkbooks out. Hopefully, we will be more reserved in letting them in on the latest and greatest. Let them buy Eurofighters and Rafales lest we have to deal with them in the future.
Also, if you want a spankin' new F-16 you can still get one for a few more years. The production is being moved to Turkey.
The export F-22 will be a different animal according to my sources. Many of the capabilities of the airplane will not be needed by the IAF.. There will be different capabilities needed for the JASDF.
Given our current economic state and the stimulus provided I can see the line re-opening for more USAF F-22s as well as foreign versions sooner rather than later.
As of maybe a year or two ago F-15E model derivatives could still be purchased new. I am fairly sure the tooling is still in place for them. However, this may have changed recently.
There are many cases where nations have chosen the more capable F-15 or the more cost effective F-16 over the F-18. The F-18 is, as in everything else, a compromise in price as well.
