I can't help but read that as you acknowledging Ukraine deserves some of the guilt of wanting to join NATO instead of just the USA's fault, which is definitely not what I meant. Russia is the lone guilty party in this invasion, or more specifically Putin, I feel pretty awful for the poor soldiers who are getting killed in foreign land or forced to play role of occupier to hostile locals. People who understand his concerns about NATO are people who have bought his lies.

Question: Whose fault was the Cuban Missile crisis and post-crisis economic sanctions of Cuba?

Mostly the fault of the USA. But lets not forget the ridiculous scale and number of military interventions Cubas worldwide. They were hardly an innocent bystander during the cold war but a very active opponent.
