Sullivan says it better than me
Despite your spin, there is really no excuse.
Money quote
We are almost two years into a conflict and critical defense weaponry is not available to soldiers who might die needlessly as a result. This is not that complicated. When Rumsfeld said, "you go to war with the Army you have," he was apparently forgetting that we went to war months and months ago. The fact that soldiers are still unprotected, that we still have too few troops there, that prisoner abuse is still occurring, that the borders are still not even close to being sealed, that the insurgency is still threatening the entire future, that we still haven't confronted the question of our global manpower needs ... well, these issues go to the heart of the question of Rumsfeld's and Bush's competence.
"Anyone who's been reading the milblogs over the" best part of the last two years knows that they have been complaining about it from the start.
It's not a case of adapting quickly - it's a case of not adapting policy period.
As to the notion of using IEDs as bombs under roads....
Hint: These used to be called mines. Don't try to consuse the issue with different terminology.
Also, you're ignoring where the explosives used in these IEDs came from.
another hint: Not the Syria, Iran or the Oil Ministry building......
Almost feel like saying Arf for some reason.
