And now tell that NATO escalates conflict not Russia. There no talk that nuclear weapons can be deployed in Finland or Poland and now Russia first deploy it to the border with NATO. BTW, if they want to fear out Finland, it really makes much sense to deploy intercontinental missiles there.
Deploying nukes to any border is nothing more than sending a political message, considering (all?) countries with nuclear weapons have the ability to stick them to the top of the missile that can fly to any part of the world. Hence the name "intercontinental". To be fair, NATO was formed to secure peace in Europe, countering the threat posed at the time by the Soviet Union. Why would such pact continue not only to exist, but to evolve AND spread eastward to Russia's borders past the Soviet Union collapse? Can you comprehend why Russia doesn't like that?
