It's impossible to deport 10.5 million. You cannot unilaterally renegotiate. You may be able to lie well enough to get people to think otherwise though.Impossibilities are not policies. They are lies.
Enforcing our laws is impossible?
Renegotiating bad trade deals is impossible?
LOL!
If those 10.5 million can move here, they can be moved BACK.
Unilaterally? Not sure what you mean. Sure, there will be multiple sides to such negotiations. Trump is an experienced negotiator who as leader of the largest economy in the world will have TREMENDOUS LEVERAGE.
And the fact that he will be negotiating with American interests as his goal will be a huge improvement over the last 5O years.
