The surge is well underway in Iraq, and by some reports it’s already making a big difference. We contacted the blogosphere’s man-on-the-spot in Baghdad, Michael Yon, by satellite phone, and got his take on how things are going. Some important bits: The dispersal of troops out of big bases and into Iraqi neighborhoods has had a big impact — somewhat like the “community policing” approach in New York and elsewhere — and is generating a lot more intelligence and assistance from ordinary Iraqis. “Just being there makes a huge difference,” says Yon. But don’t expect overnight results: “The surge itself will go on well past summer,” and it’ll be Fall before we can tell if the trends are good or bad.

Listen to the whole thing — he’s also got some interesting takes on changing tactics and changing press coverage.
