Your link is to a page on the Heritage Foundation's website. Heritage is a well-known, right-wing pro-corporate/pro-oil/pro-plutocratic propaganda think tank, funded in part by the Koch brother's oil tycoon family, and started by Coors. A quick trip to their Wikipedia page will give a taste of the sort of high quality human beings they are associated with (http://en.wikipedia.org/wiki/The_Heritage_Foundation), such as the Kochs, Reagan, Novak, Kristol, Bennet, Cheney, Boehner, Gingrich, Scaife, and Pat Robertson. And they have partnered with organizations like AEI, the Hoover Institution and the Wall Street Journal. Because Heritage has such a public track record of on-going spin and disinformation I would not trust them for any objective, non-distorted arguments.

Furthermore, it's pretty well-known among historians that in wars it is primarily the poor and the working middle-class, who die or suffer predominately, either as soldiers or civilians on the homefront, or as prisoners. The rich and their sons are disproportionately able to avoid harm, and especially in the case of weapons contractors or supply companies, oil suppliers, or banks, are often able to profit handsomely from wars and militarization. This is not controversial and is a repeated pattern going back at least a thousand years or so.

Also I looked at their report and it's cherry picked and very carefully worded, with several sloppy arguments, often contradicting themselves in the matter of a few sentences. Typical stuff for them.
