No it's not irrelevant. The West has made repeated plays to bring the former Soviet republics into its fold and the Russians are reacting accordingly. They're not stupid and have decided to do something about it after this latest bungled attempt to subvert the original Ukrainian government.
Ask yourself how would the U.S. would react if the Russians attempted to interfere in Canada, Mexico, or the Caribbean? Remember the Cuban missile crisis? Grenada?
“The West has made repeated plays to bring the former Soviet republics into its fold and the Russians are reacting accordingly.”
That is not the case. The West did not try to bring Ukraine and Georgia into the fold. As has been stated, the West rejected this.
Former nations that have been subjected to Russian dominaton such as Poland and the Baltics have been brought in and rightly so. They know without Nato and US protection they are vulnerable.
Ukraine and Georgia, former Republics of the Soviets/Russians do NOT wish to be absorbed by the Russians, but are being forcibly annexed.
