But I don't really see the point in accusing USA of cowardice. They're engaged in the most conflicts in the world. They're dumb, expansionist, arrogant and a plague to this world, but they're not cowards!
The United States is a country being run by the big corporations. They engage in so many wars, so that the corporations (especially those in the oil and gas, defense, and banking sectors) can profit out of it.
