In old fashioned one-on-one confrontations with nation states (or schoolyard bullies) muscle power can be a leading asset, but when confronting a new era of  wide-spread technological empowerment of disparate populations, unrestrained muscle power becomes self-defeating clumsiness. The musclehead approach of this administration and most of the Republican candidates will for now and for the future lead to Gulliver-esque results for this nation and those who align themselves with it. What's happening in Iraq is the future; they're learning from it, but we certainly don't seem to be doing the same.
