So we should have refused to fight the Germans and Japanese after they declared war on us?
The whole concept that war is about capitalist profits, very fashionable after WWI, is of course ludicrous. War is very risky, and businesses hate risk. There might be some companies that can take advantage of the distorted markets and make tons of money, but for every business that profits there are probably three that go bankrupt. Ever notice that the stock markets fall when it looks like we are going to go to war? War is bad for business. A few will profit, most will suffer. If anything, the "business class" are a bunch of appeasers.
Like I said, this concept of capitalists lusting after war was very popular after WWI. This and other similar delusions regarding the nature of war led directly to appeasement and thus WWII. Hopfully, we will not let such idiotic thinking again guide our foreign policy.
