Article 5 is the threat, so yes. NATO and USA started this war. Committments have been made for 30+;years that Ukraine would not enter NATO. Russia has seen NATO grow at its borders for years. Norway, Estonia, Latvia, Lithuania, Poland, and Finland all have joined NATO, most in the last 20 years. Missle systems have been installed in these countries. America would not allow Mexico and Canada to join such an opposing force and we would be in the right.
In the past, the areas of Donetsk, Luhansk, Kherson, and Zaporizhzhia in Ukraine have held referendums that favored joining Russia. Lenin gave Russian lands to Ukraine so these areas are not going to surround Russia with NATO. This war could have easily been prevented by not provoking the bear.
Article 5 is a defensive clause, and poses no offensive threat to Russia. No military force was imminently threatening Russia's sovereignty. If Russia actually viewed NATO as a real offensive military threat, they would not have pulled nearly all of their forces off of their borders with the alliance and thrown them into Ukraine. NATO threatens nothing but Russia's imperial ambitions.
Canada and Mexico have no reason to join a defensive alliance agains the United States because the United States does not behave like an unchecked imperial power hellbent on conquering its neighbors. If American indicated seriously that it had an interest in stealing territory from either nation, they would be completely justified in seeking the protection of a defensive alliance.
Russia's terrible behavior and propensity for conquest are what cause its neighbors to flee for help and protection.
Finland and Norway joining NATO can directly be attributed to Russia's invasion of Ukraine. Those nations were extremely unlikely to ever make the move to join the alliance. Despite half hearted talks of doing so, Ukraine was also extremely unlikely to join NATO any time in the near future.
At the same time, individual nations are allowed to make decisions for themselves as to what alliances they align themselves with. It is not Russia's right to determine the fate of every other nation in Eastern Europe.
Russian referendums in the occupied territories, and every election in their own borders this century for that matter, have lacked any characteristics of free and fair elections and are widely documented as heavily rigged and predetermined. This really only takes a few minutes of research to prove.
2022 Annexation Referendums in Russian Occupied Ukraine
2014 Donbas Status Referendums
2024 Russian Elections
Internal soviet SSR border drawing over 100 years ago is not a valid pretext for conquering and murdering your neighbor and we should not entertain them as such.
At the end of WWII, the rules shifted from empires to rule of law. Every nation must stay within their borders and may not redraw the maps using violence. It is not a perfect system, but it has spared us from another global conflict in the decades since and given us an unparalleled period of global peace. Let us not abandon it now.
In the end, this completely unnecessary and unjust war will leave Russia battered, more corrupt, poorer, and weaker than it ever was before while also accelerating the demographic collapse which will doom it to irrelevance.
