If the Americans do move the embassy to Jerusalem, and eventually the rest of the world follows suit, it will mark the end of Palestinian hopes for a two-state solution.

Specifically in reference to Iran, Donald Trump will not be able to renegotiate the nuclear arms pact. His attempt to do so will alienate all the European powers involved and will cost a number of US companies some very lucrative contracts. It is a losing proposition for him and for the US. Much more so than for Iran, who will turn more and more to Russia and China as trading partners.

The question is: Will Trump's ego allow him to reconsider any negative moves that he now might have in mind? Such reconsideration is really out of character for him.

If Trump takes an aggressive anti-Iranian stand, I suspect it will complicate his relations with Russia; how much so, depends on what else Trump does, particularly about participation in NATO.

Trump often acts in delusional ways. I think he is a man who has always made his own rules and gotten away with it. Enough money will do that for you. However, he has also gotten away with it because he has operated in limited contexts - mostly in the realm of business.

Trump might well choose to renege on US obligations (so much for the sanctity of contracts!) and no doubt he would have the agreement of Zionist politicians like Schumer. But the consequences will be the increased isolation of the US - particularly from Europe, whose businesses will just move into Iran while US companies will lose out.

Donald Trump has no sympathy with underdogs. They, including the Palestinians, are just "losers." So he will bring words and action together as Netanyahu wishes.
