If you play a game of chess, you play with 16 pieces per side. If you play well, you win, if you play badly, you lose. Either way the player is accountable.
What one does not do is place extra pieces on the board, taken from someone else’s chess set, to subsidise bad playing or create an unfair advantage. That is essentially what mass immigration is, placing extra pieces on the board: broadly speaking, the Democrats/Labour Party/Left do it to import voters and gerrymander politics, and the Republicans/Conservatives do it to get cheap labour and/or ponzify the economy
The chess board the nation state, the player is the government, the pieces the people. So long as the population is sovereign, the government is accountable. But if the government (state or corporate) can choose whatever population it likes, by importing new people and displacing existing ones, it is unaccountable
Trump is essentially enforcing the rules of chess and bringing government to order. The globalists want to destroy the nation state, so they have unaccountable control
