> There is absolutely 0% chance or even any rational thought or discussion that has happened by the leadership in Russia on this topic.

All military and intelligence chiefs of the European nations that share a border with Russia disagree with that and warn that their societies must be prepared for an invasion within 2 to 5 years after the war in Ukraine ends. What you call "outlandish sensational claims" by "primary school children" is something they take very seriously and it has fundamentally reshaped their approach to defense policy. Sweden, most notably, abandoned 200 years of neutrality, joined NATO, and began hardening its vulnerable points, such as the island of Gotland, which was demilitarized in 2005. Now Sweden has re-established a military presence on the island, brought back heavy weaponry, and is building up a defensive force. Why does an island in the middle of the Baltic sea need tanks, air defense systems and fighter jets on high alert?

Finland, known for its progressive policies, left the Ottawa treaty that banned anti-personnel mines. Why do you think they did that? Estonia, Latvia, and Lithuania are building bunkers and digging defensive lines on their border with Russia. Latvian news reported just today that the government is considering dismantling rail tracks connecting to Russia to make them unavailable to invading force. Not to mention Poland's buying spree: Poland is acquiring hundreds of rocket artillery systems and a thousand tanks.

Are they all foolish children who don't know what they are doing? The looming threat of a Russian invasion is the sole reason Northern and Eastern Europe maintain militaries at all. There is no other threat in the region. Their militaries could be disbanded overnight if Russia were to vanish into thin air.

  > Cuba and Russia were never in a FORMAL military alliance or pact, since that would've provoked an immediate US invasion.

It doesn't change the fact that in practical terms, the military cooperation between Cuba and the USSR was much deeper than the relationship post–Cold War NATO members have had with the older members. The newer NATO members have received only a promise of assistance in the event of an invasion. Cuba received actual tanks, submarines and fighter jets.
