A report from Iraq
This seems to be to be a very balanced view of what's going on. You can read the report, and the conclusions. Of course, the author is no Jon Stewart, but I'm sure he does the best he can with his background.
(It's educational to compare the report with the newspaper account of the report. How balanced is the news article?)
The chance of success in Iraq on the current course is small, but increasing.
The chance of success in Iraq on the Democratic Party road is absolute zero.
I believe the Democrats in Washington know this. You can draw your own conclusions from that.
