Those who loudly proclaim "America First" and call for the US to stop acting as the world's policeman sound idealistic, but the reality is much more complex. Holding the position of global reserve currency is never free.

What is the foundation of monetary hegemony? Hard power. Without strong military and political influence, you simply cannot maintain reserve currency status. Both history and current events prove this point.

So the question is simple: if you accept giving up this global financial advantage, then we can discuss whether the US should reduce its involvement in international affairs. But if you want to preserve the benefits of reserve currency status, you must recognize the costs. The two cannot be achieved simultaneously.
