OK , I hear what you are saying but NATO expansion is more complex, IMO..
Now here's a peace deal:
That Russia withdraws from the Ukraine provided that the US does not object to Russia reversing the Cuban Crisis and basing its WMDs there. AND that the US does not object to either Russia or China basing WMDs in Venezuela or other South American/Central American/Caribean countries...in short rescind the Monroe Docterine
As such and over time both the US & China-Russia would have WMDs based close to one another to enable 1st strike capabilities.
Its called reflexivity..or "what's good for the goose, is good for the gander"
