Why should the president of an invaded country have to negotiate with the invaders? They can leave and then it’s all over.
Also it’s for you to say only Ukraine is taking people off the street. Putins been throwing prisoners on the front line. He is notorious for locking up any vocal dissenter… sooooo how are you not including him in this equation?
You want to see people arrested for saying things. How about you just settle on calling them idiots and moving on?
