There probably will be cutbacks in the numbers the US purchases and will instead buy more F/A18s but to much has been invested in the F35 project to cancel it. Some countries have invested hundreds of millions of dollars in itse development, the US has invested even more. The F22 is scheducled to be closed down once all the USAF get their planes and F35 is going to be to eventually replace their older planes like the FA/18s. Israel may have to wait longer for its planes but it will get them eventually. The F35 price might be flying away but the project itself is still safely on the ground.
