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.
Me as a person, I'm not the president of the NBPA (National Basketball Players Association). I don't even know what to say. I'm not like this perfect, buttoned-up, suit-and-tie guy.
