NATO “expanded” solely thru voluntary membership - no misery, no lives were lost, and no destruction occurred ...
*******
Thd real dispute is between ideologies. NATO membership is indeed voluntary; but its members are spreading socialism, environmental extremism, and LGBT all over the world, which makes it more dangerous than a Russia fighting in its own backyard.
except Russia isn’t fighting just “in its own backyard”
it’s doing its dirty work by invading other countries “backyards” ... that’s the problem, and that’s why NATO is still needed
