Thanks to Blackfive for bringing this to my attention.
There is a group, calling themselves "Resolve to Win", composed of retired servicemen who returned from duty in Iraq, who have decided to march from South Carolina to Washington DC. They have the expressed goal of increasing American resolve for victory in Iraq. They are now in day 12 of their 16 day march, intending to finish in 4 days, in front of the Lincoln Memorial.
I haven't heard anything about them in the mainstream media. But they have a well written and well planned blog that can be found at http://www.vfwwebcom.org/ResolveToWin/.
In my opinion, the possibility of victory in Iraq has never been a question. The American military is orders of magnitude stronger than any other on the planet. The question has always been weather or not the American people have the fortitude to let the military do its job.
