If nations lost the right to exist because of crooked leaders
the US would not exist. Russia wouldn’t exist. China
wouldn’t exist. On and on it goes.
You just get none of this on any level.
By your reckoning, the Soviet Union deserves to exist. Face it: nations come and nations go. That’s the way of the world. No nation is “guaranteed existence.” When it becomes weak, lawless and corrupted, it can and will often fall.
Red China will fall because it is evil and doesn’t value human life. If Russia embraces and sells out to decadent globalist “values” like Western Europe or Ukraine, it will fall like its predecessor. The U.S. has embraced decadence, corruption and anti-Christian/anti-White and sexual depravity and the clock is running out on it, too. Sometimes what replaces the old and corrupt/decadent is better than before, sometimes not.
