Belmont Club summarizes information about the ongoing battle in and around Qaim on the Iraq/Syria border, in which the Marines are crushing a large contingent of insurgents. More information at Fourth Rail; a second post is here.
It seems that having reduced most of the insurgent bases in Iraq proper, the US is finally starting to close down the supply lines from the border. A commenter on Fourth Rail speculates that all the diplomatic pressure on Syria in the past weeks has been in preparation for Operation Matador, to prevent the insurgents from escaping across the border. The Army has said that the mission was planned for some time, so this is very likely the case.
Actually, stop reading this post and go to The Adventures of Chester. He's been liveblogging the mission for some time. I'm headed there as soon as I post.
