The "War On Terror" cannot be won by attacking nations and nation building. Terrorists exist in cells throughout the world and fight for many reasons. They have declared that they strike because of US occupation and bases in the middle east. The best response to terror attacks is to destroy responsible cells and with special forces surgical operations.
The "War On Terror" is an ideal war to support a large defense budget. It is infinitely expandable and how can victory be declared? Who will sign the surrender agreement? Comparing it to WWII by calling it. WWIII is rediculous and insulting to that effort.
Where in the world is our Military? In 144 nations according to an article in the American Legion Magazine, 2/2008. Some of the largest are:
Republic of Korea 27,000
Iraq 168,000 (now ~ 140,000)
Afghanistan 24,000 (increasing by 30,00)
United Kingdom 10,000
Continental US 876,000
At sea/in port 115,000
When President Eisenhower left office, he warned of the "military industrial complex". Consider the logistics, facilties and equipment costs to support the complex. The 2010 Defense Budget is $663 Billliion.
