So far there is NO significant change planned in overall U.S. Mideast policy. This was shown clearly in the recent Senate cross-examination of Biden’s new appointments as Secretary of State, Defence and as National Security chief. All were praised by
both parties’ leaders, including those closely supporting Trump policy in the past.
While the mess left behind by 1) U.S. support to the Saudi War in Yemen; 2) the official characterization of the Houthi militia as a “terrorist” organization, and 3) Trump’s unilateral tearing up of the internationally-agreed upon JCPOA agreements, will all need to be addressed, nothing indicates a fundamental change in policy is being prepared.
Of course the present situation remains highly unstable, especially in Syria and Iraq — where U.S. policy is determined by the perceived Iranian threat to Persian Gulf oil interests and by the Israeli lobby.
Conflict may indeed break out in the future. It is even possible in the next 4 years the huge and besieged American Embassy in Baghdad may be evacuated, perhaps to set the stage for encouraging a new Civil War and an intended and purposeful splitting up of that unfortunate country.
