1965 - Strategic bombing of military bases, industry, roads from the PRC and other key targets in N. Vietnam. In parallel, forward deployment of not only B-52s, but massive invasion forces in "Essarn."
1966 - Invasion from "Essarn," then occupation by US forces of the entire length of the Ho Chi Minh Trail, encompassing the eastern 1/5 of Cambodia and the entirety of the "boot" of southern Laos (Screw the UN and screw the ranting "Bundung" generation of Nehru and all other 3rd world crybabies. Call us a bully, I don't care.)
Late 1966 early 1967 - Invasion of N. Vietnam. Unconditional surrender of the Communists. Decommunization of N. Vietnam and Laos commences. Establishment of a strong SEATO unquestionably led by the USA. Establishment of bases, similar to those in Germany, throughout SE Asia including nuclear warheads and road mobile SRBMs and IRBMs ready to strike the PRC.
I cannot begin to count our blunders in SE Asia since the end of WW-II and am sad to consider how we shall yet pay for them in the future great war. Appeasement, accomodation and trade with Communists only postpones the inevitable.
