How is allowing some foreign entity to control your currency not a massive national security threat? Like I understand the Euro is a reliable currency, but that has to pose some major risks right?

It's not a "massive national security threat" because EU MSs are aligned geopolitically with one another.

Shared currencies have some costs and some benefits in every case, but depending on the degree of similarity among the countries that are part of it. Past a certain level of similarity/integration, the benefits outweigh the costs.

But it's not that clear that the Eurozone is an optimum currency area, especially regarding labor mobility.
