Iraq is accused of various provocations, and American ships and bombers are being sent to the Middle East. The consensus is that neither side wants war. But, National Security Advisor John Bolton did advocate bombing Iran before he joined the Trump White House, and the president has exchanged dire threats with Iranian leaders.

They’re still part of the nuclear deal Trump withdrew from;  Iran wants their help in dealing with economic sanctions, and they have to maintain their business ties to the US.
