Actually, I don’t think the United States or anyone else is fooled. I think they don’t care. Nobody has a realistic vision of Yeladim Viyelados… Every new administration feels pressured to show that they are making progress in Peace in the Middle East. The Israeli government knows it will make no peace but are pressured to show that they are not the obsticle to peace. The trick is to try to talk more that you act and to procrastinate. I think Bibi is a great procrastinator, at least when it comes to giving away land.
The question is, who is everyone trying to impress? The Navi mocked us for trying to impress our neighbors in vein. The Medrash says that all those who tried making peace with the Bnei Keidar landed up with Bizyonos. The Rambam also mentions that you can’t speak peace with these people. I doubt anyone thinks you can.
