The US could indeed pressure Quatar over slavery, or Saudi Arabia over Khashoggi and human rights, or China over Uighur Muslims and emissions, or Russia over Ukraine and corruption, or Iran and North Korea over nuclear weapons, or Israel and all its neighbours to get a move on with the peace process, or the UK about the Irish border and laundering Russian money, or Mexico about border security and the drugs trade, or Myanmar about restoring democratic rule, or Japan about whaling or Turkey about treatment of their Kurdish minority.

But pressuring them all at once, and hard enough to get results? That could leave the US in a lonely spot.
