Now let me think. The Cuban missile crisis started when the soviet union was about to put nuclear missiles on Americans doorstep. American reacted with the threat of war.
and that the US is trying to find an "off-ramp"
I think the off ramp was in the letter delivered to nato that said neutral Ukraine and no nato on Russia's doorstep.
If the west was not drowning in its own propaganda and hubris it might have noticed these things.
I think one thing the west has noticed is how the majority of the world are not backing the west and are in some cases pushing back. I also think those who rule the west are staring at the collapse of Europe and wondering how that is going to be good for business.
