Johnson points out that we are the world's greatest producer and exporter of arms on the planet, spend more on our armed forces than all other nations combined - while going deeply into debt to do so, and station over 500,000 troops, spies, contractors, dependents, etc. on more than 737 bases around the world in 130 countries (even this is not a complete count). Further, statistics compiled by the Federation of American Scientists analyzed by Gore Vidal show 201 military operations initiated by the U.S. against others between the end of WWII and 9/11 - none of which are directly resulted in the creation of a democracy.
Many have accused Bush II of violating international treaties - Johnson, however, is the first that I know of to make the point that our Constitution (Article 6) makes all Treaties made under authorization of the U.S. to be the supreme Law of the Land." Thus, much of Bush's international actions are not only objectionable on moral and practical grounds - they are illegal as well.
As for why few of the world's billion+ Muslims like the U.S. - estimates range from 500,000 to 1 million Iraqi children killed as an outgrowth of U.S. sanctions. Johnson also goes on to document U.S. blocking contracts to improve Iraqi water and other utilities just prior to our invasion. Then there are the matters of torture and secret renditions. (How do these acts reduce terrorism?)
The situation in the U.S. has gone downhill as well - Bush II's administration ignoring/violating the Freedom of Information Act, questionable wire-tapping, letter-opening, Internet surveillance, etc.
What is the dollar cost of these misadventures? Joseph Stiglitz, Nobel-prize winner in economics, estimates a total cost to-date of Iraq II alone at about $2 trillion - includes ongoing veterans benefits, equipment repair, etc. Meanwhile, the U.S. is trying to militarize space - further adding to our military expenditures and indebtedness.
Finally, Johnson sees our military costs eventually bankrupting the U.S. (if our escalating trade deficit doesn't first), aka Rome.
