Buchanan, a senior advisor to presidents Nixon, Ford and Reagan was a Republican presidential hopeful in 1992 and 1996 and the Reform Party candidate for president in 2000.
Co-founder of The American Conservative magazine, Buchanan was an original host on CNN's Crossfire. He currently is a commentator on MSNBC, a regular on The McLaughlin Group and a frequent guest on Hannity and Colmes on the Fox News Channel.
An author, Buchanan's latest book is called Churchill, Hitler and the Unnecessary War in which he argues that World War II was avoidable. Buchanan argues had Britain not given a war guarantee for Poland and had not gone to that nation's defense there would not have been a war and there would have been no Holocaust. And the British empire would not have collapsed.
Had Britain not declared war on Germany, he says, Hitler wouldn't have come west. If Buchanan is right, and World War II was unnecessary, then what of contemporary decisions to go to war? For example, Buchanan believes the United States, is engaged in an unnecessary war in Iraq. And a war with Iran over its nuclear weapons aspirations, he says, would also likely be unnecessary because Tehran, he suggests, can be isolated and controlled diplomatically.
