That's foolish. If Russia wins in Ukraine, they would have the two strongest armies in Europe. European states simply don't have enough ordinances and gear to survive a long war.
The idea that Russia would “have the two strongest armies in Europe” if it won in Ukraine doesn’t make sense. A defeated country’s army doesn’t magically become part of the victor’s forces. Ukrainian soldiers wouldn’t serve Russia, many would withdraw, go underground, or continue resisting.
Even in a hypothetical total Russian victory, Moscow wouldn’t “gain” a second army. It would inherit a hostile, traumatized population and an ungovernable territory, not a usable military force. And in any case, Europe’s combined militaries (and economies) are still far larger than Russia’s, so the claim simply doesn’t hold up.
Did you link the wrong article? This one says they are only working on maybe making that happen, and the article is only a month old, so they haven't conscripted any yet?
So true; Russian MO is to use ~18-60 year old males from occupied territories as cannon fodder. Europeans should be flooding Ukraine with weapons (and other kinds of support) and thanking their luck that somebody else is willing to risk their lives and use them against the onslaught that would otherwise be directed at the EU countries.
