IN TODAY’S WALL STREET JOURNAL, AN OPED FROM MICHAEL YON:

It is said that generals always fight the last war. But when David Petraeus came to town it was senators – on both sides of the aisle – who battled over the Iraq war of 2004-2006. That war has little in common with the war we are fighting today.

I may well have spent more time embedded with combat units in Iraq than any other journalist alive. I have seen this war – and our part in it – at its brutal worst. And I say the transformation over the last 14 months is little short of miraculous. . . .

This leads us to the most out-of-date aspect of the Senate debate: the argument about the pace of troop withdrawals. Precisely because we have made so much political progress in the past year, rather than talking about force reduction, Congress should be figuring ways and means to increase troop levels. For all our successes, we still do not have enough troops. This makes the fight longer and more lethal for the troops who are fighting. To give one example, I just returned this week from Nineveh province, where I have spent probably eight months between 2005 to 2008, and it is clear that we remain stretched very thin from the Syrian border and through Mosul. Vast swaths of Nineveh are patrolled mostly by occasional overflights.

We know now that we can pull off a successful counterinsurgency in Iraq. We know that we are working with an increasingly willing citizenry. But counterinsurgency, like community policing, requires lots of boots on the ground. You can’t do it from inside a jet or a tank.
