This shameless argument assumes  perhaps correctly  that no one in this country remembers anything. So let me provide a reminder: We already did make that mistake again when we walked away from Afghanistan to invade Iraq in 2003  and we did so at the Three Amigos’ urging. Then, too, they promoted their strategy as a way of preventing another 9/11  even though no one culpable for 9/11 was in Iraq. Now we’re being asked to pay for their mistake by squandering stretched American resources in yet another country where Al Qaeda has largely vanished.

To make the case, the Amigos and their fellow travelers conflate the Taliban with Al Qaeda much as they long conflated Saddam’s regime with Al Qaeda. But as Rajiv Chandrasekaran of The Washington Post reported on Thursday, American intelligence officials now say that “there are few, if any, links between Taliban commanders in Afghanistan today and senior Al Qaeda members”  a far cry from the tight Taliban-bin Laden alliance of 2001.

The rhetorical sleights of hand in the hawks’ arguments don’t end there. If you listen carefully to McCain and his neocon echo chamber, you’ll notice certain tics. President Obama better make his decision by tomorrow, or Armageddon (if not mushroom clouds) will arrive. We must “win” in Afghanistan  but victory is left vaguely defined. That’s because we will never build a functioning state in a country where there has never been one. Nor can we score a victory against the world’s dispersed, stateless terrorists by getting bogged down in a hellish landscape that contains few of them.

Most tellingly, perhaps, those clamoring for an escalation in Afghanistan avoid mentioning the name of the country’s president, Hamid Karzai, or the fraud-filled August election that conclusively delegitimized his government. To do so would require explaining why America should place its troops in alliance with a corrupt partner knee-deep in the narcotics trade. As long as Karzai and the election are airbrushed out of history, it can be disingenuously argued that nothing has changed on the ground since Obama’s inauguration and that he has no right to revise his earlier judgment that Afghanistan is a “war of necessity.”

Those demanding more combat troops for Afghanistan also avoid defining the real costs. The Congressional Research Service estimates that the war was running $2.6 billion a month in Pentagon expenses alone even before Obama added 20,000 troops this year. Surely fiscal conservatives like McCain and Graham who rant about deficits being “generational theft” have an obligation to explain what the added bill will be on an Afghanistan escalation and where the additional money will come from. But that would require them to use the dread words “sacrifice” and “higher taxes” when they want us to believe that this war, like Iraq, would be cost-free.

The real troop numbers are similarly elusive. Pre-emptively railing against the prospect of “half measures” by Obama, Lieberman asked MSNBC’s Andrea Mitchell rhetorically last week whether it would be “real counterinsurgency” or “counterinsurgency light.” But the measure Lieberman endorses  Gen. Stanley McChrystal’s reported recommendation of 40,000 additional troops  is itself counterinsurgency light. In his definitive recent field manual on the subject, Gen. David Petraeus stipulates that real counterinsurgency requires 20 to 25 troops for each thousand residents. That comes out, conservatively, to 640,000 troops for Afghanistan (population, 32 million). Some 535,000 American troops couldn’t achieve a successful counterinsurgency in South Vietnam, which had half Afghanistan’s population and just over a quarter of its land area.
