Tell me about Tet then, GX. I didn't know it was considered a failed offensive. I heard it demonstrated the ability of the NVA & VC to mobilize a nationwide attack and the failure of our intelligence to get a whiff of it. With all its associated issues like movement of munitions, extensive planning and communications, didn't it show the enemy to be a lot better organized than we gave them credit for? And us to be more poorly informed than we would have liked to believe?
-Militarily it was a disaster for the communists. The V.C. lost upwards of 100,000+ soldiers during all 3 phases of the offensive. The V.C. were finished as an effective fighting force and the NVA took complete control of the war against the South Vietnamese at that point. The North wasn't able to mount a serious offensive until 1972, The Easter Offensive, which the North was defeated by the South, with help from U.S. air-power.
-Our intelligence had a whiff or two or three of the operation. We knew something was coming, but Westmorland believed the Communists would strike at Khe-Shan in an attempt to destroy a major U.S. installation and win a huge P.R. battle like the North did against the French at Dien Bien Phu. Westmorland was correct, the North did strike Khe-Shan, but it was a head-fake engineered to distract which it did.
-Tet did show that the enemy had the capability plan, execute and somewhat sustain a large scale, multi-front offensive. But, the North, specifically the V.C., couldn't totally sustain it over the offensives 3 phases, which ended in August. It was a one shot deal, they tried, failed militarily and that was it. Mass defections from the V.C. to the South occurred as well. In the end, Westmorland had the Communists right where he wanted them, out in the open in a stand-up fight where he could bring huge concentrations of firepower to bear. Find, Fix,Kill.
-Tet was a huge political/propaganda victory for the communists. It didn't have to be, but LBJ, the military and an increasingly anti-war media foiled that for the U.S. and the South Vietnamese. Remember that Tet happened after LBJ's "Light at the End of the Tunnel" speech and the war was going on 5-6 years for the U.S. After Tet, LBJ started a troop withdrawl and that was really the beginning of the end.
-If we maintain commitment, start Linebacker-like no holds barred air operations earlier and go into Cambodia before/directly after Tet things would have turned out differently. Or boot Westmoreland for Creighton Abrams and his COIN policy, too.
-It was bad, really bad for the V.C. and the NVA. Of course the worst was to come for the V.C. after the fall of Saigon in 1975.
I think I hit the major points, if not, someone fill in the blanks.
