What is the free world "fighting" for in Ukraine? I for one have difficulty accepting the objective is trading "energy independence" from Russia for Ukraine's capital contributions to EU27 political cohesion and economic stability.

erm whose strawman is that? Linky?

threats, posed by the sovereignty of the Russian Federation

Well, we know whose strawman that is.
Yours, Oui's and Pooty-poot's.

What threat who posed to the sovereignty of the Russian Federation is a fascinating question.
How the invasion of Ukraine was supposed to fix the problem is no longer very interesting, because said invasion has opened the possibility of said threat becoming real at a future date
(by revealing the piteous state of the RF's military, and by degrading its capacities)
