We could have saved ourselves a whole heap of heartache and treasure if we stuck to the original model of using SF teams on the ground and B52s in racetracks overhead.
That didn't give the army generals a reason d'être to justify a large army budget for the next couple of decades though. We went boots on the ground for one reason. Large land armies have become irrelevant.
I hope those in the decision chain hang their head in shame over the suffering they caused, that's on both sides.
