Earlier quoted context omitted.
> Nothing will change in the US if Ukraine falls tomorrow. It certainly will when Putin moves on to invading Poland or Finland. The whole point of holding the line at Ukraine is because everyone believes Putin won’t stop there.
After the unexpected difficulty of the Ukraine war, how likely is it that they would try to extend themselves even further, against stronger countries than Ukraine?
"Putin is too sensible to invade Ukraine" was the argument people were making the day before he did. My guess is these are the same people who now say "Putin would never invade Poland".
