Biden mentioned 350,000 Russian KIA.
Ukrainian death toll has been reported as two to three times the Russian's which would mean over a million dead so far if true.
Which is why it isn’t true. Traditionally, the attacking forces receive greater casualties than the defenders do and this is true in Ukraine, also.
Recent counts suggest that the Russian casualties are 3x Ukraine’s, but have risen to 6x the Ukrainian casualties thanks to growing parity of artillery and other weapons and the style of attack the Russians favor that results in high Russian casualties.
The Russians have lost an astonishing number of tanks and APCs and have had to adjust to this reality, leading to even higher than usual Russian casualties. And soon, F-16s and other weapons will be joining the battle to save Ukraine from Putin and Russian losses will continue as now and will likely increase.
More to the point, as they watch history repeat itself, former Soviet countries are coming together to aid Ukraine, too. They don’t want to go back to those bad old days under the old Soviet ways as Putin clearly does want to do.
The only “win” for Putin is for him to quit killing Russians in Ukraine and go back home and stop attacking and killing his Slavic family neighbors like he is doing now.
