Tell me again how a more powerful European Union would be a solid ally of America, given their leadership:
If Federica Mogherini didn't exist, the world's autocrats would be trying to invent her.
As the European Union's high representative for foreign affairs, she is a tireless advocate for engaging rogue states. Few diplomats though have pursued this kind of engagement with such moralizing puffery. In Mogherini's world, diplomacy with dictators should not aim to transition these countries to open societies, but rather to prevent conflicts at all costs.
The future imperial socalist EU state won't be any less hostile to American interests than the current proto-empire it is, with the subjugation of European nation-states still incomplete.
The EU imperial state the apparatchiki in Brussels want to build through their "ever closer union" project will be bad for America, bad for Europe, and horrible for Europeans who still value freedom.
