The author presents considerable evidence that this is, indeed, the case. But, is this reason so surprising given the history of the US? Read General Butler's book entitled War is a Racket on how he saw his career:
I spent 33 years and four months in active military service and during that period I spent most of my time as a high class muscle man for Big Business, for Wall Street and the bankers. In short, I was a racketeer, a gangster for capitalism. I helped make Mexico and especially Tampico safe for American oil interests in 1914. I helped make Haiti and Cuba a decent place for the National City Bank boys to collect revenues in. I helped in the raping of half a dozen Central American republics for the benefit of Wall Street. I helped purify Nicaragua for the International Banking House of Brown Brothers in 1902-1912. I brought light to the Dominican Republic for the American sugar interests in 1916. I helped make Honduras right for the American fruit companies in 1903. In China in 1927 I helped see to it that Standard Oil went on its way unmolested. Looking back on it, I might have given Al Capone a few hints. The best he could do was to operate his racket in three districts. I operated on three continents.If you had read independent historical sources, you would know that both world wars in the 20th century were primarily over which capitalist empire ruled the world: Anglo-American or German. As we know, the Anglo-American capitalists won and they have continued fooling the American people about their wars with some of the more recent wars being the Gulf of Tonkin incident and the Vietnam War, the Kuwaiti incubators and the first Gulf War, the Racak massacre and the war in Kosovo, Iraq’s weapons of mass destruction and the second Gulf War, and threats of a humanitarian nature to the people of Libya and the Libyan war).
Now the Empire is threatening another war in the Middle East and pretending that it is for humanitarian reasons while it is actually over pipelines which are essential conduits for control of energy in their competition with Russian and Chinese capitalists. To sell the public on these wars, they must always justify them using humanitarian or security reasons. The latest form of this old ploy is now being used again to fool the American people.
