Are you suggesting that we spent 50,000 lives plus 100's of thousands of casualties plus our nation's treasure and prestige with the objective to fight NVM to a stalemate?
No, the objective was to force a halt to NVM's aggression against the South. You have no knowledge whatever of the war and its history, either political or military, if you think otherwise. When, for example, did our forces enter North Vietnam and attempt to occupy it?
