forhorn, you're likely right that the US is over reacting to the possible threat of middle eastern pilots. However, it's somewhat understandable that the US might be a little sensitive. After all, did not four aircraft flown by middle eastern "pilots" do their level best to destroy human life in the US? Further, was this action not praised by the overwhelming majority of the residents of the middle east?(and by Muslims world wide). The US government would be stupid not to conduct a threat analysis in these circumstances. If any government doesn't wish to cooperate in this effort, no problem: Keep your aircraft outside US airspace. Perhaps in your view the UK should have been more cordial to the German pilots who visited in WW2.
