That would be admitting you got it wrong. It'll actually be "It was all due to sabotage (wrecking) by Antifa. ICE stormtroopers are on the way to round them up now. Incidentally Antifa is anyone who didn't vote for Trump".

The one problem will be that, at least at the lower levels, the US still has a mostly functioning judiciary so they'll have to either set up some parallel system to sentence people, e.g. the Military Collegium of the Supreme Court of the USA, or set up a special judiciary to do it, e.g. the People's Court (Volksgerichtshof).
