He was warning about nato expansion to the russian borders being unacceptable for mane years. Did the west understand that? No! I guess he's signaling the importance of the issue.
That’s a mischaracterization of the threat. The threat was to prevent any interference in Russia’s invasion of Ukraine, which is sovereign country. Putin’s threat of nuclear war was not made in the context of NATO expansion nor the deployment of nuclear arms near Russia’s borders, etc. Nuclear weapons were in fact removed from Ukraine at Russia’s behest.
"Russia will use nukes once ukraine joins nato?" It doesn't make any sense.
The nukes were removed from ukraine like in 91. Usa wanted that no less than russia, it was a deal.
In a democracy, governments are accountable to their citizens. So if the war against Ukraine bothers you, you should contact your representatives within your government to do something about it.
