If Ukraine was a house of cards, then they would have collapsed in February/March when paedoBiden gave up on it and the Ukrainians were fighting off Putin’s army on their own.
It is increasingly clear that this war is ordinary Ukrainians fighting against Putin’s army. This is not Zelenskyy directing it.
The ordinary Ukrainians are running this, so if Zelenskyy goes, the Ukrainians will keep fighting until Putin leaves.
In contrast, on the Russian side - get rid of Putin and that house of cards collapses. This war is Putin’s war.
