Deja vu all over again

Jacob Weisberg warns Democrats:

The Lamont-Lieberman battle was filled with echoes and parallels from the Vietnam era. Democratic reformers and anti-establishment insurgents weren't wrong about that conflict, either. Vietnam was a terrible mistake for the United States. But like Iraq, Vietnam was a badly chosen battlefield in a larger conflict with totalitarianism that America had no choice but to pursue. In turning viciously on stalwarts of the Cold War era like Lyndon B. Johnson, Hubert Humphrey, and Scoop Jackson, anti-war insurgents called into question the Democratic Party's underlying commitment to challenging Communist expansion. The party's Vietnam-era drift away from issues of security and defense—and its association with a radical left hostile to the military and neutral in the fight between liberalism and communism—helped push a lot of Americans who didn't much like the Vietnam War into the arms of Richard Nixon.
