Not much of a parallel as far as warfighting goes... in retrospect, I guess I'm jumping the gun as as far as Iraqization goes too.
Vietnam was being invaded by the North, openly supplied by China nad The USSR. We didn't go after the supply chain (Haiphong Harbor and the Rail Line from China) till the war was all but over, and then only to force the North to the Treaty Table. The North had big support from several other sources as well.. all of them openly shipping arms and material... their ships steaming happily past the Tonkin Gulf Yacht Club toting SAMS and Tanks to Uncle Ho.
When we pulled out, we left several NVA divisons in place in the south, per treaty. Although we promised renewed military support and air cover if the North broke the treaty and renewed it's attacks, we broke the deal and abandoned the south completely to it's own devices when the NVA struck in force. The North rolled into the cities in the south with armor and artillery, the ARVN officers melted into the population leaving the troops leaderless. Although there were pockets of ARVN resistance, the North had a pretty easy cakewalk.. once they got rolling, it was over in about a month. The VC didn't take South Vietnam, the NVA did.
In Iraq, it seems we've got a Insurgency ala the VC.. no NVA regulars with artillery, tanks and anti-air nets waiting in the wings to mow down the local security troops with better firepower and modern artillery. As long as we keep the security troops better armed and supported than we did the ARVN troops, as long as we keep the supply lines for the insurgents shut down (from Syria & Iran and their heavy weapons/ammo supplies & material) maybe the Iraqi security troops can keep control.
Maybe.
I'd be happier with Iraqi security forces handling the house to house stuff and US Troops handling the hammers and anvils. The 'patrols' have gotta stop.. non indiginous walk-a-bout troops are just targets over there.. just like they were in Vietnam.
Either way.. I'm watching this all unfold with not just a little bit of angst.. cripes; I hope our kids get outta it soon. Would be par for the course to have the new Iraqi governmnet sell us out up the road.. gawd whotta mess this turned out to be.
