Further, the peace talks didn't even start for a protracted period thereafter, over a dispute on the shape of the table and who would get to sit where - meaning the N Viets would not allow S Viet to attend as an equal. Nixon escalated and expanded the attacks in SoutEast Asia as we withdrew in constant effort to bring the N Viets to an agreement.
It was Johnson who launced a "Christmas Bombing". Nixon finally won teh peace by mining the N Viet harbors and choking off their supplies.
I lived through it and I don't know where you got the fantasy that Nixon delayed getting a peace treaty deliberately for 4 years. That is pure nonsense. And Nixon got a treaty that would never have been violated if he remained as president. It was the democrats in Congress who gave N Viet a pass on a giant tank attack after Nixon resigned (once again the honorable approach versus scumbag Clinton and his puppet Albright).
But then I can't take you seriously after you just said that moron Albright and scoundrel Clinton were more "true" to our nation than Nixon and Kissinger. It was Clinton who TOOK THE CHICOM'S ILLEGAL CAMPAIGN CASH, sold them advanced computers for their nuclear missile program, and embraced them as "strategic partners" as they were emerging as our greatest threat.
LBJ launched Rolling Thunder.
