"Yes he has a right to support them & supply weapons etc....." - Not under international law. This is why he is lying about it.
"All elected leaders lie about such things,so i guess he has
as much right to lie as any other....." Tu quoque. We are talking about Putin.
"Had Ukraine's elected government not been overthrown by
parties funded by the US/EU,Putin wouldn't have this mess on his doorstep." Ukraine is a sovereign nation. He is not responsible for its politics any more than the West is. He is responsible for invading parts of Ukraine and supplying arms to other parts. Which brings us back to his responsibility for the folks he arms.
