I understand what your are writing. But this war is not mine. So I can and I judge or analyse it differently. For me, your charge on Putin and respect of treaties is part of the same debate.
Western powers started in not respecting treaties and rules. Western powers started to invade others countries and to decide what was right and what was wrong.
Do you think that Serbs believed that France would bomb them? They have a monument in Belgrade saying "love France like France loved as".
And about Ukraine, what do you think Russians were feeling in watching anti-Russian chants and demonstration: betrayed?
