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.

Consequences of acting in Donald Trump's usual egocentric, "I make the rules," way can be quite dangerous for all of us.

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.

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.

Trump's election means that you have a US government that will no longer do one thing and say another.

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.

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.
