Well, mateys, let me clue you in a Pyrrhic Victory is.Its when you win Battles overwhelmingly,inflict heavy casualties,but take unsustainable expenses and human losses and eventually lose the war because you are demoralized and thoroughly whupped. Doesn't that describe what happened to the United States in Viet Nam?
The North Vietnamese won the war ,they united their country, they kicked out a corrupt American backed Catholic regime in South Viet Nam. Today, we have full relations with Viet Nam, and are building factories and buying cheap products. does that sound like the Viet Namese lost? Lets face it ,they were tougher,fighting for their homeland, and able to survive our napalm,our dropping more bombs than we did in WW2,our defoliation ,our internment camps, our Rock and Roll ,etc.
Our misguided excursions in Afghanistan and Iraq will have the same results. Our casualties are less because we largey stick to our bases and bribe warlords to do our bidding.In the end we will effect no lasting change, and once again bankrutped and disallusioned we will leave a muddle, and return to a collapsing nation.
