Everyone knows how Donald Trump negotiates at this point. He takes extreme positions; he creates as much leverage as possible through threats of nuclear war, tariffs, and sanctions; and he waits for his opponent to surrender. If that doesn’t work, he takes whatever he can get and spins it as a “win.”
Most world leaders have concluded the best way to deal with him is to collaborate with him on the illusion of an American “win.” Presumably for domestic political reasons, the Iranian leadership is refusing to play that game. In fact, they are engaging in Trumpian tactics of their own by escalating. They apparently believe that the combination of pressure from other countries and Trump’s own lack of enthusiasm for war will ultimately cause the US to back down.
Don’t bet on it. Remember, Trump is surrounded by people who want war, and he isn’t going to accept humiliation on this or any issue. The Iranians, in my opinion, are making a serious mistake.
