We all know that from a moral point of view that Russia did wrong in invading the Ukraine.
But Geopolitics -particularly where great powers are involved- its all about power, not what is right or wrong.
Was the US right in invading Vietnam? Was the US right in invading Iraq? Was the US right in invading Afghanistan?
Bit it did.
The only international organisation to act as global policeman is the UN and it is powerless when it comes to putting troops on the ground (by donor nations) when a Great Power is involved who has Security Council Veto Power.
Russia has such veto power.
So in summary, your "pulpit-like " preaching on the right-wrong of this war is futile and your libelling/abusing other posters who don't agree with you is "mongrel" to say the least, IMO.
