Ukraine can fight this with whatever they can get from around the world.
You ignored the entirety of my point, which is that Ukraine has signaled that they want the conflict to end, but their masters in Washington and the EU are pressing them forward regardless. Donbas has been functionally independent from Ukraine for almost ten years now, and only two of those with Russian troops supporting it. It’s not Ukrainian territory anymore in any way that matters.
Meanwhile Brazil went back to their last progressive president after Bolsonaro’s failure, and Bolivia has foiled two attempted coups by reactionary forces. Venezuela and Cuba also remain strong, with the latter being possibly the most democratic country on this planet.
In Africa, the most notable “democracies” that have been overthrown in recent memory were all client states of western countries whose previous governments cannot in good faith be said to have been representative of the people.
The Middle East is pretty bad, what with Israel going full fash in the past year. It’s not like they haven’t been edging for decades, though.
But in Asia, the only country that might be more democratic than Cuba is China, and they’re as strong as they’ve ever been. Since that’s 1/5th of the population of this planet living under one of its premier democratic governments, I’d say the prognosis for global democracy is fine.
