NATO was explicitly formed as a defensive alliance to deter and repel a foreign military alliance that disappeared in 1991. A recent president rightly scoffed at the current Russia as nothing more than a gas station.

This is not the Sudetenland, Putin is not Hitler, Biden is not Chamberlain.

Most of the NATO members have ZERO interest in this fight. Germany, especially. They want it to end, quickly, without triggering massive energy cost spikes, a global recession, or a massive refugee problem.

There is no way a military confrontation with any nuclear armed power ends in anything but a draw, after heavy loss of life. NATO is not the solution to this mess.
