Quotes from the same author

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.

Most of the time, teachers who talk about the Middle East do not know the history, culture or present context of the problems they are discussing. So they go to the media, which quote government or academic "experts" (who often are no such thing) or journalists who, by virtue of working for the media, are supposed to know what they are talking about. In the end they know little or nothing beyond a standard line that reflects the perceptions of the US government and its special-interest supporters. That is what the students get. Indeed, that is what we all get.

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.

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.

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.
