No, Dallas has a point. It is always instructive to turn the map around.
Looking at the beginnings after the Revolution we see the communists entirely ringed with countries, including the old European States, all intent on crushing the revolutionaries.
After 20 years they were again attacked and Moscow threatened. They then established a secure two country buffer zone to the west. The weakest link was Czechoslovakia which bordered both west and USSR.
Then you have a nuclear armed and now bellicose USA fervently opposed to the perceived threat from communism and you are surprised they are paranoid.
