Only problem here is that Trump is famous for not paying his debts.
He doesn’t play bureaucracy games; he just stops spending money in certain areas and lets the bureaucrats scramble to make it OK.
In other words, I see the US stopping all engagement with NATO and a EU/US tariff war in the future — IF he can pull it off in four years.
It’s all a matter of perspective; when you’re that far right, ultra-conservatives are way more liberal.
