invasions into other states such as Czech Republic (which is like Ukraine, divided into ethnic groups that really don’t care about their central overlords),
I regularly go to Czech Republic and don't understand this comment. Czechs very much care about their democratic government and are sick of this war. It has increased the price of most everything. There are no "overlords" there. They are not a fan of Russia I can assure you, them having occupied their country from 1968 to 1988. The feedback I am getting is that Zelensky is viewed as a narcissistic and crooked sleezeball. Many Ukrainians are in their country instead of staying and fighting for Zelensky.
No one is afraid of Russia invading Czech Republic from there that I am aware of. I talk with people from there every few weeks or so. Czechs believe this can be resolved diplomatically, but NATO keeps it going along with the USA by sending Zelensky hundreds of billions of $$$.
The West is getting scammed by Zelensky. Maybe its Zelensky dancing in high heels that compels NATO and the USA to flood him with money?

Anyway, the Czech's have a better understanding of the complexities of the war than western europe and especially the USA.
This is a good article on the situation.
