He should retaliate against the UN, first step should be telling them their US headquarters status is void, leave by the end of next year. 70 years of nothing but subsidizing a bunch of low lifes who would be better suited to having the next HQ in Uganda or Yemen. They can raise the level of the economy of either place.
For instance the UN building is suddenly unable to be occupied and will take many years to repair. So perhaps it should be relocated.
And some think, not my idea but I like it, that this AID money staying with us was always on the back burner but now he can claim a reason for keeping it.
