This, at least in my mind, has never been a matter of "if", but instead a matter of "when". According to the Washington Post, the "when", has occurred and according to their poll the majority of Americans are now against the war in Afghanistan. Popularly known, even by Barack Obama, as the "good war" or the "necessary war", the Washington Post is now saying popular sentiment has turned against it:
A majority of Americans now see the war in Afghanistan as not worth fighting, and just a quarter say more U.S. troops should be sent to the country, according to a new Washington Post-ABC News poll.
Among all adults, 51 percent now say the war is not worth fighting, up six percentage points since last month and 10 since March. Less than half, 47 percent, say the war is worth its costs. Those strongly opposed (41 percent) outweigh strong proponents (31 percent).
This change of perception has been driven by the left, who previously claimed that Afghanistan was indeed the only proper war worth fighting:
Although 60 percent of Americans approve of how Obama has handled the situation in Afghanistan, his ratings among liberals have slipped, and majorities of liberals and Democrats alike now, for the first time, solidly oppose the war and are calling for a reduction in troop levels.
Overall, seven in 10 Democrats say the war has not been worth its costs, and fewer than one in five support an increase in troop levels.
Among the right, the war there is still seen as worth fighting and winning:
Republicans (70 percent say it is worth fighting) and conservatives (58 percent) remain the war's strongest backers, and the issue provides a rare point of GOP support for Obama's policies. A narrow majority of conservatives approve of the president's handling of the war (52 percent), as do more than four in 10 Republicans (43 percent).
Interestingly, as the article states, this is a "rare point of GOP support for Obama's policies". And it pits both Obama and the GOP against the left and, I would guess, a Congress which will eventually reflect the constituency against the war that the numbers above show. There's a reason for that.
Congress is on a "dollar hunt" right now to pay for their favorite domestic agenda items. Afghanistan (and Iraq) are places where some dollars can be stolen. Lack of popular support and money to be had should be more than enough impetus to begin the "cut and run" mantra in earnest.
Apparently for the left, since it is no longer a blunt rhetorical instrument with which to beat George Bush over the head, Afghanistan is no longer the "good and necessary war".
