The military is the body that brings stability its also the only one that doesn't get irrational and start calling for war when emotions start flying over political issues. Israel has not asked the US to give anything new just what would have been given anyway but has been suspended because the army carried out a coup and US law forbids the giving of aid to a government in place because of a coup. When you have the pro Morsi protesting one side and the anti protesting the other side you have the military in the middle trying to balance things. You want to keep the military sweet then bend the law and give them the aid that was originally going to be given before all this started. Its actually pretty logical to avoid rocking the boat to much at a time when the country is so unstable.
