World wide conditions are much the same today as they were in Europe prior to WWII. All it will take is a little spark to re-ignite the conflagration that actually began with WWI and never put out. In general mankind is too proud to admit error and too stupid to learn from its mistakes. Putins reminder about Russia’s nuclear capability should not be dismissed. If, God help us, that cat is let out of the bag WWII will look like a church picnic.
The only scum capable of using nukes are the Muzzies. Even NK’s leader Jong-Un is not that stupid.
What concerns me is how China responds to Putin’s moves. More specifically, if Russia “gets away” with its encroachment into Eastern Europe, then China will behave in a similar manner by expanding and pressuring countries such as Malaysia, Singapore, Korea, and Japan. Therein lies the real threat.
