Many in Washington point to Mr. Trump’s divisive management style, Mr. Tillerson has little reservoir of good will left in the capital. He was already judged “the nation’s least influential top diplomat in recent memory”, as Rich Lowry, editor of National Review, the conservative journal, put it. He has alienated his own department with deep budget cuts and a diffident style while never bringing in a full team of his own. He has made few friends in Congress or the foreign policy establishment. He has maintained such a low profile that his clout was doubted from the start.
