The New York Times reports:
The Trump administration considered imposing tariffs on imports from Australia last week, but decided against the move amid fierce opposition from military officials and the State Department, according to several people familiar with the discussions.
Some of President Trump’s top trade advisers had urged the tariffs as a response to a surge of Australian aluminum flowing onto the American market over the past year. But officials at the Defense and State Departments told Mr. Trump the move would alienate a top ally and could come at significant cost to the United States.
The administration ultimately agreed not to take any action, at least temporarily. The measure would open yet another front in a global trade war that has pitted the United States against allies like Canada, Mexico, Europe and Japan, and deepened divisions with countries like China.
