Each autumn, the United Nations General Assembly draws the world's nations to New York — including those whose governments stand in deep opposition to their host. The United States, bound by a 1947 treaty obligation, has once again granted visas to Iran's delegation, permitting their participation in the assembly despite decades of mutual hostility. The approval is not a gesture of goodwill so much as an acknowledgment that international law endures even where diplomacy has long since frayed, though movement restrictions remind all parties that protocol and trust are not the same thing.
