You would think that going to war would be a serious affair and that a leader would look into the matter before risking the lives of their countrymen.
As can be seen by this clip. Our world leaders in the west do not do their own research. They take orders from above and say what they are told to say to their people in the best interest of the people that elect them. Unless you own the economic system and the media then you are not responsible for their election. You just pretend you are like everyone else in a representative democracy.
