TRUMP TROLL number 1:
Offer Provincehood to Puerto Rico. Run TV ads there. Get the population talking about it.
2): Canadian UN Ambassdor asks for UN Vote on Moving UN headquarters from New York, as USA is not longer a "united nation". Offer Toronto or Montreal, nearby.
3) Call for meeting of democratic nations to elect New "Leader of the Free World'. Use EU rules for "Democracy", which the USA doesn't meet, so don't invite them.
4) Openly offer a bribe, ask him how much he wants.
