NYT:

For Mr. Biden, a longtime senator who prided himself on his experience in foreign relations, the role represents an evolution in his own thinking, a shift from his days as a liberal hawk advocating for American involvement in Afghanistan. Month by month, year by year, the story of Mr. Biden's disenchantment with the Afghan government, and by extension with the engagement there, mirrors America's slow but steady turn against the war, with just 37 percent supporting more troops in last week's CBS News poll.

Arianna Huffington:

It's been known for a while that Biden has been on the other side of McChrystal's desire for a big escalation of our forces there -- the New York Times reported last month that he has "deep reservations" about it. So if the president does decide to escalate, Biden, for the good of the country, should escalate his willingness to act on those reservations.

What he must not do is follow the same weak and worn-out pattern of "opposition" we've become all-too-accustomed to, first with Vietnam and then with Iraq. You know the drill: after the dust settles, and the country begins to look back and not-so-charitably wonder, "what were they thinking?" the mea-culpa-laden books start to come out. On page after regret-filled page, we suddenly hear how forceful this or that official was behind closed doors, arguing against the war, taking a principled stand, expressing "strong concern" and, yes, "deep reservations" to the president, and then going home each night distraught at the unnecessary loss of life.

Well, how about making the mea culpa unnecessary? Instead of saving it for the book, how about future author Biden unfetter his conscience in real time -- when it can actually do some good? If Biden truly believes that what we're doing in Afghanistan is not in the best interests of our national security -- and what issue is more important than that? -- it's simply not enough to claim retroactive righteousness in his memoirs.

Though it would be a crowning moment in a distinguished career, such an act of courage would likely be only the beginning. Biden would then become the natural leader of the movement to wind down this disastrous war and focus on the real dangers in Pakistan.

Doubt he'll resign, but i think Biden's evolution has been interesting and encouraging. I was originally disappointed when he was announced as the VP candidate because he had been a hawk.
