Best American Pressure

A tariff imposed by America might spare gunboat diplomacy or even a war. It is a means of exerting influence without firing a shot or threatening bloodshed. It is likely the most benign way that a superpower can assert superior status without threat of violence or actual use of "hard power". Tying Trump's hands by revoking his authority to impose tariffs makes real conflict much more likely. As happens with alarming frequency, the United States Supreme Court just made another mistake.
