The crisis happened because the usa put bombs in turkiye which is super close to the ussr.
Now the usa has bombs in turkiye and other nato members near russia.
The issue is that we can't handle what we dish out, I guarantee if russia station nukes further than we stationed them to russia that we would freak out and threaten nuclear apocalypse.
the usa makes unnecessary enemies by acting hypocritical and basically pushing other nations around.
At one point we could have gotten russia in nato and could have slowly influenced it to be like the rest of nato.
Instead we gave them the middle finger and created a jaded enemy that wants to be the ussr again because we treated them as the ussr.
