Israel and Egypt are already doing this along the Sinai-Gaza border. Just as Obama has tossed Egypt into the trash heap, so has he left Israel alone, to deal with Iran, and very soon. There is intense cooperation between Israel and Egypt and the poor little diddums HAMAS in Gaza are eating gravel.
Jordan, Saudi Arabia and a host of other Arab states are on board with Egypt and even Israel right now because they all know, America is simply not there. America has proven to be totally unreliable at this critical juncture in history.
Obama has voted present for his golf and vacations but absent as the leader of the USA and our allies, especially the Brits shied away from supporting him. Only the Frogs seemed to want a good fight which is strange, considering the French prefer surrendering to fighting...that's how bad it is right now.
Iran of course wouldn’t be alone in such a showdown, but they are the ones—if anyone—we should have gone after after 9/11.
As to the French, I believe that demonstrates the caliber of allies that Obama and Kerry are able to attract.
