Is it impossible for a talking point to be true?
Yes, it is.
And I'm aware I'm going off-topic here but I see so much misinformation, disinformation and outright ignorant bovine excrement here in America regarding Ukraine (almost universally coming from those who profess to be Christians while making excuses for slaughter) that I can't hold my tongue on this point, partly because as an educator it is my duty to dispel falsehood when I see it and partly to defend the honor of my betrothed's homeland, a land I'm proud to have fought for, the greatest country it has ever been my honor and privilege to live in: The Republic of Ukraine.
Your entire argument of "neocons want to fight to the last Ukrainian" hinges upon the assumption that the Ukrainians do not desire to resist Russia and are only doing so at the behest of America. Anyone laboring under such a delusion has never spoken to a Ukrainian, and uttering this view in the presence of a Ukrainian is a fine way to unburden oneself of a few teeth, the hard way. As one who lived there, on the Russian border, let me make this simple. Every, single, Ukrainian, without exception, has an immediate family member who was killed by Russia and at least five ancestors within the past two hundred years who were killed under Russian occupation. They're quite aware that allowing Russia to take over will equal their extinction, and in the years I lived there I never met a Ukrainian who counted themselves as "brethren" with Russia any more than you'd find an Israeli who considers themselves "brethren" with Iran. Russia's own State Duma has openly and casually bandied about the notion of "cleansing" Ukraine of its population more than 52 times since 2010, and need we mention the two times when Soviet Russia openly tried to do so?
With that said, Ukraine's losses so far are half of Russia's (and to anyone thinking otherwise then I ask you to tell me who you think the ones are who are still slaughtering Russian troops at a rate of 800+ per day). They're not going to lose 90% of their male population by fighting. They WOULD lose that, however, by not fighting.
I'll go a step further by saying that if anyone who professes to be a follower of Christ and is not calling for Ukraine to be given the means to defend their lives and homes against Russia, who has openly declared its Hamanite intentions toward them and has bragged about the slaughter of innocents (and don't try to tell me they haven't; I speak Russian and I see it every day on their own social media), then I counsel that person to contact me as Christ's Return draws nigh, because my in-laws in the Philippines own a Catamaran, a Millstone and plenty of rope. All of the above will be of interest to such a person on that day.
