But "war is pretty bad idea" is a widely shared opinion, as war is pretty bad one.

> The same countries that stole the land? The countries that waged countless unjustified wars of oppression based on lies?

Yes, these countries. Approximately all countries stole land (even if this land was stolen from Venezuela: guess how Venezuela acquired it? and "give it back to local tribes" does not work, because they stole it from other tribes).

Also, approximately all countries waged some unjustified wars of oppression based on lies.
