How Did Trump Let This Happen?

Aside from the national humiliation and breach of trust with allies, we have a remarkable development with President Trump’s sudden and still entirely unexplained decision to green-light a Turkish invasion of northeastern Syria.

President Trump chose this moment to drive a massive wedge between himself and the overwhelming majority of his own party. At a critical moment he chose to open a second front … against himself.
