Let's be real, Ukraine is NOT going to win. Russia is going to keep the territory it has under its control. Russia is going to grind down anything Ukraine sends.
Besides tens of thousands of casualties, how much territory did Ukraine reclaim during it's much awaited/hyped spring/summer/fall offensive last year?
I had read that the average age of the Ukrainian soldier is 40+ years old. If that's true, it has no more young men left to sacrifice! What happens when there's no more Ukrainians? Where are they going to get more men to replace the barely trained men they currently send to their deaths? They're already sending barely trained women to fight. No amount of money/arms is going to do any good if there's nobody to use it. England and Sweden are openly talking about conscription.
With all the folks/farmers protesting against their governments in Europe, Germany, France, etc, you think those people are going to willingly go to war for Ukraine?
Are you pro-ukraine/war folks willing to send our military, YOUR kids, grandkids to fight and die for another country while ours is literally being invaded by millions of people? Is it worth it to risk a full-scale military conflict with Russia over Ukraine to include nukes, never mind the current state of our conventional military or the fools running it?
BTW, What does the average American citizen get out of war in Ukraine? I'd argue, nothing!
Its easy to cheer war on when one isn't actually fighting and safely behind the warm glow of a computer screen typing away, isn't it.
To add: In the end, the US government will abandon Ukraine, just like it abandoned everybody else when it's politically untenable.
