The same unwashed of the 60's are at it again.
My only critique for the South Vietmanese is why didn't their Army fight as hard and fanatically as the North Vietmanese soldier. If they had fought hard and not constantly relying on the Americans to do all the heavy lifting, they would not be slaves today. Corruption also killed the South Vietmanese Army. They operated very similiar to many non modernized Asian military of its era. Generals and senior colonels were preselected from elite families (patronage system), and payroll was allocated to division commanders based on the number of soldiers in the unit. Commanders skimmed the money and what was left over went to the soldiers. There was less incentive to commit troops to battle, because casualties would reduce the number of men (thus payroll amount and amount that can be skimmed). Many South Vietmanese commanders hesitated to go into combat unless it was absolutely necessary. The good news is the US military learned from Vietnam and we emphasized on building cohesive battalion size units first and not massive divisions when we assist foreign allies in later Low Intensive wars.
