If Donald Trump shows signs of backing out of Europe, the Russians might be willing to stay out of his confrontation with Iran. If he follows Obama's program in Europe, things might be different.

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.

My guess is that Trump will begin withdrawing troops from Europe at a slow pace. He will demand a renovation of the Iran Accord and get nowhere with this. There might be more US sanctions on Iran. However, the Iranians will not compromise with Trump, and barring a naval confrontation in the Persian Gulf, it will be US businesses that will suffer and Trump's frustration level that will go up.

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.

Trump's tendency is to rub shoulders with dictators. We have seen this with his attitude toward Russia and also toward the present dictatorship in Egypt. He might start to cozy up to the Gulf dictators as a way of trying to scare the Iranians. This could lead to a naval confrontation in the Persian Gulf.
