It is true that the EU has worked with NATO. However, it's not clear that America needs all the military force it has since a lot of it is quite cleary force projecting on economic adversaries.

Suggesting the EU "needed" this is a bit misleading. And I say this as an American exasperated at our refusal to reduce force projection on foreign nations.

The EU definitely "needed" it. Aside from France and the UK, EU countries are pathetic militarily.

NATO was originally formed to be a defense alliance of democratic countries against communism and Russia. Russia, while a threat to the United States, poses more of a threat to Europe (for geographic reasons) than to the United States.
