Once you read the article 5, you’ll find out that it says that in case a NATO member is attacked then NATO will convene and each country will decide individually what level of support it will provide. There is no obligation for countries to send troops or get directly involved. And of course if Poland is stupid enough to attack Belarus or intervene in Ukraine then there is no obligation to do anything at all.
Of course, even if NATO did agree to fight all together, it’s pretty clear that NATO is in a dire shape having sent much of what it has to Ukraine at this point. US has literally admitted to running out of basic stuff like artillery shells now.
Y’all can downvote all you like of course, but that’s not going to alter reality. Maybe it’s time for people to reflect on the past two years of war in Ukraine and how everything western media claimed about the conflict has now turned out to be completely wrong.
