Umm…No! Is Z irrational, desperate? 1) He’s not willing to compromise…yet; 2) his Willingness to interject the U.S. in a direct conflict with another superpower that’s undergoing a stated existential crisis is reckless.
He’s been accused of being on Cocaine. This might explain what’s fueling his mindset.
Until Conditions warrant otherwise: get in as much munitions, intelligence & support to the Ukrainians as you can as long as long the will to fight is high and they’re punishing the Russians.
Avoid use of tactical nukes.
Adjust as necessary. Know when to throw in the towel to save lives, etc.
