You're going to get a lot of hate for posting this, because it's disinformative crap and Putin is a war criminal.

If you want to see a talk that does actually bring this perspective -- more or less, that Putin does have valid reasons for seeing his security threatened by the expansion of NATO -- without the propaganda crap and without somehow trying to say that that justifies Russia invading a sovereign nation to rape and murder its civilian citizens, then watch this talk by John Mearsheimer. Inflammatory title aside, it's excellent.
