The US military doesnt care what pissant euro's want. Its the same thing with the implimentation of 7.62x51 and the FAL/m14 tardfight. The US sets the pace since its responsible (by way of spending the most money of defense and military) for fighting for european countries.
As for armor? US civilians are largest user of armor...
Yes, The US carry the bulk of the weight within NATO, but being harmonious with those allies has been the stated intent for the last 70+ years. A contributing factor to the 9mm switch in the 80s was NATO congruency.
And as for armor..... Both China and Russia have been equipping their infantry with armor. Although sporadic reports are showing Russian armor in Ukraine isn't quite what it was advertised to be anyway.
Unless your statement was an inference to potential tyranny, which would not surprise me either.
