Can you not see that appeasement is pure folly?
The hypocrisy is that people who have lived in Australia for 50+ years are calling for the US to go defend Ukraine. Why not call on Australia to go and defend Ukraine?
How about Ukrainian athletes whose homes are bombed and families killed? And the West refuses Ukraine permission to strike Russian territory for fear of escalation. Ukraine has no choice as it has to keep the West happy or their weapons will dry up. What is fair about that?
If Ukraine falls, Putin will attack other former USSR nations next. As they have already. Ukraine has substantial resources that Russia can use. It's not a buffer from NATO nations, rather a stepping stone for more aggressive action. That's why Poland is rearming as quick as they can. They know that if Ukraine falls, they will be the next target.
