Even with the mJor US action against North Vietnam, a Soviet, not Chinese client, would you really see Mao/ Gang of Four begging forgiveness to Brezhnev to return to their subservient role of the '50s to act as a united front?
Yes. In the mid-1960s, North Vietnam was just as much a Chinese client as it was a Soviet one (Chinese-Vietnamese relations in 1940s-1970s was an unusually good one by historical standards, with a split only developping in the mid-70s), hence China's willingness to fight to defend it. With China now committed to defend North Vietnam against US aggression and American soldiers now killing (and being killed) by American personnel, the Chinese suddenly have an interest in acquiring more Soviet weaponry and the Soviets have an interest in the Chinese acquiring those weapons. If what amounted the same Chinese leadership were ultimately willing to do it in Korea, I see no reason why they wouldn't be willing for Vietnam.
Well for one north vetnam and China never had a very good relationship, ho chi min when he was in charge nerly caused a rupture with China when he supported the ussr on the border issue with China (before the sino-sovite split even happened mind you) , only reluctantly supported chia grabbing the parcels (and emidiatly changed there stances the moment the south was conquered) and the simple fact that it took less the 5 years after the war before these countries whent to war shows the dislike runs deep.
In reality, Chinese aide outstripped Soviet aide until 1965, being estimated at 3/4ths total foreign military aide to North Vietnam between 1950 and 1970. But good job revealing you don't actually know anything about the subject.
In reality, it actually started out with an exceptionally excellent relationship. The Vietminhs campaign against the French in the early-1950s was virtually bankrolled by the PRC, with most of the guns used to shell Dien Bien Phu were overwhelmingly pieces that had been either manufactured by the PRC or had been captured from the Nationalists by the PRC. Chinese military advisors trained much of the Vietminh's personnel throughout the 1950s and the bulk of economic aid recieved by North Vietnam originated from China over that decade.
Diem needs to stay, so he can now order the ARVN to go invade North Vietnam he ordered the Army to prepare for it, now knowing that the US would do that, its plausible if Diem stays he coordniates with the US and Start an invasion to unite the country with full fledged us support
Have any sources on that? Also shows your the one that's dosnt really know anything if you think that sino-vetnam relationship was good during that time, for example most of the guns used in Dien Bien Phu were captured Japanese peaces and Chinese advisors were only involved after the war was over.
"In comparison, altogether the Viet Minh had moved up to 50,000 regular troops into the hills surrounding the French-held valley, totalling five divisions, including the 351st Heavy Division, which was an artillery formation equipped with medium artillery, such as the US M101 105mm howitzer, supplied by the neighbouring People's Republic of China (PRC) from captured stocks obtained from defeated Nationalist China as well as US forces in Korea, together with some heavier field-guns as well as anti-aircraft artillery." -Battle of Dien Bien Phu
"In addition, a 'political advisory group' was also sent from China to northern Vietnam in 1950, led by Luo Guibo. Luo went to Tonkin to “pass on China’s experience in financial and economic work, the rectification of cadres’ ideology and working style, government work and mobilization of the masses.” Between 1951 to 1954, the Chinese helped the Vietnamese in training their military commanders; reorganizing their defense and financial systems. They also helped the Vietnamese to mobilize the peasants to support the war through land reform campaigns. Overall, there was a massive transfer of the Chinese experience of making a revolution to the Vietnamese." - From the China in the Vietnam War article linked above.
Not feasible due to potential international condemnation against bombing densely-populated targets. Economic targets are often close to population centers. About military targets, most North Vietnamese military targets were either mobile such as their Anti-Aircraft defense and RADAR systems, or easily to construct such as secret dirt/concrete airfield.
This was already implemented by OTL. Most Soviet aids were disrupted due to the mining of North Vietnamese water, but aid still flowed into North Vietnam through the Chinese-Vietnamese border.
Causing intentional destruction to civilian centers is not very productive to propaganda, but you have just secured the loyalty of the North Vietnamese people for Hanoi, not that they never lacked it anyways. This would definitely hinder the ability to supply NLF forces tho, since you just destroy their logistics hub with nuclear fire.
Communications during the 1960s were very easy to fix when it was just a few telephone/telegraph lines. During the war, the North Vietnamese repair team could just repair the communication lines faster than the US could destroy it.
