Agree with some of the posts pointing out the landscape has changed immeasurably. Now, admittedly I've had a drink, so the argument may not be too coherent (thank God for spell checker!) but I have this notion that future wars will be fought through a combination of cyberspace (ie viral attacks on major installations - power infrastructure and such) and those with money flexing their fiscal muscle where countries can be bankrupted by threat of lack of investor confidence.
Sure, your nuclear missile can cause widespread devastation and death, but nothing on the scale/longevity of the effects of removal of investment and a dos/viral attack on a country.
Theoretically, you could take vast swathes of territory out.
Like I say, I've had a drink so could be a million miles off, but that's what I reckon. Watch out for the geeks. They will rise and fulfil the prophecy:
"Blessed are the geeks for they shall inherit the world."
