You weren’t alone in Iraq and Afghanistan. Also, fighting against talibans and Iraqi rebels is a bit different compared to the war in Ukraine so I’m not so sure your US troops are more “warfighters” than the European troops.

How many non-US combat troops do you think were involved in Iraq and Afghanistan? How many troops do you think European NATO members will commit to a hot war in Ukraine? I agree that the Ukrainians are battle-hardened in a way few other countries are now (besides Russia of course). Ukrainian soldiers also have valuable experience in drone warfare and will have much to teach the US and its allies about 21st century conflict. US military is going to have to modernize some of its personnel and capabilities for new technology, but at this moment, I'd pit the US military against any other in the world. And it's not close.

But for how long will you be able to have the strongest and most modern military in the world if you start losing money because of trade wars and/or other countries stop buying US weapons and so on? I believe it won’t be good for your economy, or ours, if we stop being friends and allies.

This is why Europe must remilitarize and police its own neighborhood on behalf of western security. Probably not going to happen under the EU, which has no ability to assert muscular sovereign leadership. There is no unified Europe at the moment. Better for Europeans to ditch the EU and double down on NATO as a military alliance of sovereign states.
