Ukraine supporters and perpetual war

For those American citizens who support Ukraine, I have a question:

If, during the Cold War, if Mexico and Canada had sought to join the Warsaw Pact, would you have supported that? Putting Soviet missiles within short range of where you live.

Yet that is the mirror image of what Russia is quite reasonably opposing, allowing Ukraine to become part of NATO and put various offensive weapons within short range of its territory.

I 100% endorse the Russian POV in this.
