It is upsetting that you get downvoted. I think people in the US are thinking that a war is impossible or something, and looking for a stereotypical response.

Instead, for an eastern and central European countries, a war is the real threat. The chance to lose a war with Russia backed by China is very real.

And the reason it is real is the loss of protection from the US. It is no longer guaranteed that the US will participate once Russia invades, and that makes the invasion itself almost inevitable.

Participation of the US is important only because it has a massive stockpile of WMD. It is obvious for everyone that US is not prepared for a modern war on the ground against a real power.

Prosperity and economic growth doesn't really matter when you are threatened with losing the massive war with causalities calculated in millions.

You first want to secure and guarantee peace for the future, and then you think about economy, competition and so forth.

And massively increasing weapons production is the way to avoid the big war.
