I used to not believe in conspiracy theories, but am beginning to change my mind.
It has been said that the nations needed to become economically tied to other nations so no wars could take place. Then the populace needed to be broken up with immegrants from other nations so no group could have a political monopoly.
It appears to me that that is what is happening to Europe and the USA now.
I don't know why they would say that.
When Germany invaded France in WWII, that country was its largest trading partner.
When Japan launched its sneak attack on Pearl Harbor, the United States was its largest trading partner.
