Maybe the West will react after the terrorist russians blow up a chemical plant? Nah, will take years to investigate. Wouldn’t want a “knee jerk reaction”.
Maybe after the terrorists unleash a dirty nuclear reactor incident? Nah, could have been an accident.
Maybe after a tactical nuke is used (if they can find one that still works)? Nah, those sneaky Ukrainians probably stole it.
The russians… and the feckless West… can do thus forever.
