I’m not sure that that is correct.
I can’t think of any technical advance during a war that wasn’t just an acceleration of something that had been developed, or was starting to be developed, before the war.
Often with far-sighted anticipation of a war.
… but I fail to think of one for Iraq. If only they can figure out how to better detect IEDs. That would be a nice technological achievement. I know they were working on the sniper/fire detector, but too buggy right now.
I think this reflects a deficiency in tactical thinking and, worse, failing to address the real strategy required to win that conflict.
America long ago won the war in Iraq.
The problem is that America can‘t occupy successfully, nor can it enable its preferred government in Iraq to govern.
IED’s are no more the problem in Iraq than the SVN / American / Australian mines lifted by the VC in Vietnam were.
The military, but not central, problem is deficiencies in counter-insurgency tactics, notably by America in Vietnam and now in Iraq where the focus is on military actions by conventional forces against irregulars.
Very occasionally it is possible to infiltrate irregular forces to some effect, as Britain did in Northern Ireland courtesy of having largely the same language and culture, but it can almost never happen in places like Vietnam or Iraq.
But the central problem in all cases is the absence of a political solution acceptable to all parties, or a military force capable of crushing all opposition as North Vietnam did in Vietnam. Neither applies on either side in Iraq. So it will just go on until one side or the other gets into a position to impose a political or military solution.
I’m not holding my breath for either.
