No doubt the Left will try to blame America first for the problem, but I don’t think the Trump Administration is there to discuss philosophy.
A big factor in Trump’s success has been a realistic assessment of where the incentives are, when dealing with people, and bringing the leverage that virtually guarantees the outcome. Since they have been able to turn around the big geopolitical issues of the day with China, Russia, North Korea, Iran and Mid East so effectively; I am confident that they will be able to squeeze (and incentivize) these three countries to perform.
Those countries should have incentive enough; their best & brightest are fleeing, and they’ll end up like Mexico - completely dependent on untaxed remittances from the US.
