Buchanan is misunderstood in very many respects. I don't like his social views at all, but that guy was dead on with regard to foreign policy before and after 9-11 and the Iraq War.
In 1999, he whote a book called "A Republic, Not An Empire" where he predicted a catastrophic terrorist attack and the botched foreign policy that would follow. Sure enough, 9-11 happened, and the fucknut in the Whitehouse decided to start all kinds of wars.
Then he wrote "Where the Right Went Wrong", which was a scathing, honest, and spot on criticism of the Iraq war, naming names, showing the failure of the congress to reign in the retard in chief, and W's willingness to let our young men and women to go lose life and limb over there in Iraq over dishonest reasons while sleeping like a baby on benedryl every night.
Yeh Buchanan has his problems, but I would take him over Bush. At the very least, there'd be about 3,500 more of America's kids still alive and well, 25,000 American families not dealing with a death or maiming, and hundreds of thoushands fewer reasons for people in the middle east to hate this country.
