Donald Trump is marking his first 100 days in office with a rally in Michigan where he told enthusiastic supporters "we've just gotten started". Of course, not everyone's a fan. UK magazine The Economist is putting a battered American bald eagle on its cover with the caption "Only 1,361 days to go". But what if it's too late to reverse 100 days of rule by executive order? What if the president's already the winner of a power play with the legislative and judicial branches of government?

Among the daily test of boundaries is last week's arrest by federal agents of a judge in Milwaukee for refusing to let her courtroom become the scene of an arrest of a man wanted for deportation. That's on top of the arrest of foreign students for denouncing Israel's bombing of Gaza, the defunding of congressionally-mandated agencies, the targeting of universities and law firms, and so on.

The world's most powerful nation turning on Ukraine, abandoning the fight against global warming and arbitrarily imposing tariffs on allies has real-world consequences. So will Americans stay silent, while a 248-year-old republic veers away from democracy?
