If Russia is paper tiger as "Richard Smith" claims, Putin will stop at Ukraine and would never attack a NATO country.
All the more reason, Ukraine needs to be in NATO in order to survive. Otherwise, Putin cannot be trusted.
That's got to happen with or without the US being involved.
I'm more concerned about what has happened within the United States over the past 6 weeks.
It would seem dismantlement has only just begun. It is terrifying.
