It's hard to know how to respond to crowing by many today about the fact that only 19 U.S. military personnel were killed in the month of May. It's definitely better than April, when 54 were killed. If it jumps back up to 54 next month, will those crowing today say they were mistaken, and that "the surge is not working"? No, because more deaths mean the surge is working, too.
We have always been at "working" with the surge.
That brings us to 4,083 dead Americans. And more Iraqis than we bother to count.
