The EU is suddenly beset by enemies. Putin threatens it militarily and, to a lesser extent, ideologically; the Chinese want to swamp it with imports and neuter it politically; and now Trump wants to turn it into a vassal state. Where is this going, in the long run?
I don’t see the EU submitting to Trump. My best guess is that we will see two important developments: first, the EU will become intensely protectionist; and second, the Germans will build nuclear weapons and offer their use to Europe as a whole. Given the fraught historical relationship between the Germans and Russians, this will present a real danger to Putin if he pushes too hard.
