“the attack on the Moscow parade was a sure-fire way to start WWIII.”
I am afraid that I must point out the obvious - There is no WWIII.
So obviously, that was just just more empty Russian propaganda.
Bottom Line: Russia is going to be hit more and more at home. Restrictions have been lifted by the Germans, French, and British - and by President Trump. No more range restrictions on the use of Western weapons in Russia. All of Russia has become a free fire zone, because of Putin’s crime spree.
Russia obviously lacks the capability to fight WWIII - it can’t even successfully fight Ukraine.
Russia will obviously cease to exist as a functioning society if it attempts a nuclear weapons use.
