85 years was a long time ago. Was there any Russian threat between 1991-2007?
If you hint that the very fact of the Russian existence is a threat then the Russians are going to ignore you.
Was Cuba in its right to install the Soviet missiles in 1962?
Nobody is hinting that Russia’s mere existence is a threat. Russias perpetual imperialist designs on its neighbors is the threat. Again, the world isn’t watching US-Canadian relations with concern. Nobody in Belgium fears a German invasion despite their equally recent bad history.
Asking if another repressive communist regime was “in its right” to point missiles at the US is outside the question. The United States could easily turn Cuba into a parking lot and yet nobody fears that actually happening. Russia, on the other hand, is a perpetual bully. What did Georgia and Ukraine do to offend benevolent comrade Putin?
