Many in the west regard Iraq as illegal Mel.
As for Libya William Hague said it was about protecting civilians and not about regime change! We all know what happened there. The west removing legitimate leaderships and spreading terrorism as usual.
You have to remember most of the world organisations are simply western fronts to help keep the west in control.
Russia is very much right to bring peace to Ukraine. Maybe they can bring peace to the whole country. It really does not matter if Russian troops are in Ukraine or not. As one can see from Crimea they are welcomed as heroes and liberators from the tyranny and oppression of the Kiev junta. The Russian troops really are heroes fighting against the evil and injustice of the world.
