Sounds an awful lot like, Ukraine will fall in a day......
Or 15 days to stop the spread...
This one will also be proven untrue.
It really depends on NATO(USA) having an anti missile defense that Russia knows not of. DoD says it has no defense against the fractional orbital hypersonic missiles and we did officially shut down the rapidly progressing laser weapons that could provide that defense under Pres. Hussein.
Lord, I hope so!
