I think I finally understand the Trump Doctrine as it applies to national security. Insult our allies, cozy up to our strongmen enemies, and antagonize/provoke enemies who aren't strongmen, while attacking or undermining our defense institutions. Obviously this wouldn't be a thought out strategy by anyone, even Trump. Its not a strategy. But it is an objective summary of the actions Trump has taken. Of course nobody knows to what end this will lead. But energizing your enemies while disillusioning your friends and letting down your defenses seems to lead directly to a more vulnerable position.
