If the countries of Europe want to have a mutual defense treaty, that's up to them. If they don't have the military to support it then maybe they need to allocate more resources to that.
We are already overmilitarised compared with realistic need, or at least sufficiently armored. You speak of the countries of Europe. Thereby my comment distinguishes between different EU countries. Never occured to you, that there are drastic differences between the interests of different countries in Europe. I think it will be to Europe'a advantage, when NATO is dissolved, but it is the US which has to announce it, for reasons given in my comment.
