You said:

There is no reason to believe that at current levels of armorisation, even French and German military would be enough to defend Europe against Russia, not to speak of the rest of the 3 times such big EU.

But now you say:

We are already overmilitarised compared with realistic need, or at least sufficiently armored.

I suggest you pick one story and stick with it.  

Yes I know that different countries have different interests.  I'm tired of that being an excuse for why the United States needs to be involved.  Figure it out among yourselves.  Stop waiting for the US to take the lead in everything - including the future of NATO.
