Last week, U.S. Ambassador to Israel Thomas Nides appeared to endorse a plan for Israel to attack Iranian nuclear facilities with U.S. support. Nides's words come after recent high-level military drills between Israel and the United States intended to showcase the ability to strike Iranian targets, as well as recent acts of sabotage and assassination inside Iran believed to have been carried out by both countries. The Israeli escalations mean that the U.S. now faces the unsavory prospect of a major crisis flaring up in the Middle East at the exact moment when its bandwidth is already stretched thin because of a major war in Europe and its deteriorating relationship with China. "The decision to leave the JCPOA ... allowed Iran to restart its nuclear program and raise once again the question of what the U.S., Israel, or anyone else might do about it," said Stephen Walt ... at the Harvard Kennedy School, referring to the nuclear deal by the initials of its former name, Joint Comprehensive Plan of Action. The nuclear deal was intended to avoid the Middle East confrontation now visible on the horizon. Signed by President Barack Obama in 2015, the deal traded strict limits on Iran's nuclear program in exchange for its reintegration into the global economy. When President Donald Trump violated the deal ... this pragmatic arrangement went out the window " not only removing limits on Iran's nuclear program, but also politically empowering hard-liners inside Iran who had balked at negotiating in the first place.
