Ukraine is not the only theater of conflict in the current war between Russia and the former Soviet republic. The 30 nations of NATO are coordinating sanctions, sending supplies, and moving troops and weaponry into position to defend the alliance from a wider war. All 193 member countries of the United Nations are involved too, as the U.N. scheduled an emergency meeting of the General Assembly—only the eleventh such crisis gathering since 1950—to try to bring the war to an end.
