BRUSSELS — President Donald Trump has long been skeptical about the value of alliances. Two weeks into his war with Iran, he was seeking Tuesday to build one.
Faced with Tehran’s successful effort to cut off the flow of oil and gas tankers through a vital shipping choke point, Trump has importuned a sweep of nations to help secure the Strait of Hormuz. He has blasted Britain, Germany, Japan, South Korea and others for their reluctance. And he has revived his long-standing complaints about the NATO alliance, musing Tuesday that he could rethink the U.S. relationship with allies without congressional approval.
