Anti-War History Repeating Itself?

Charles Krauthammer points out that in the 1960's the anti-war movement resulted in the ending of the careers of some prominent Democrats and pushed the party to the left, with the result that the party lost all credibility on national security issues until the end of the Cold War. Krauthammer's suggestion that the same could be happening today strikes me as credible.

With regard to both then and now, Krauthammer points out that a debatable position on the immediate war in question brought forth a more generalized rhetoric that proved to be radical and unacceptable to the public at large in the long-term.
