The US over estimated its influence on Egypt, and when its threatened Egypt with cutting US aid, Sisi showed the US the finger and ordered new migs from Russia.
The US is overestimating its influence on Israel too. George H. W. Bush cut aid to Israel over the settlements, but Shamir continues to build, totaly ignoring the US. Today Israel is far more independent than in the 1980s and could do well without the American "aid" (which is in fact subsidy to the American defense industry).
