Uh, no. The US flew almost 700 sorties in support of the French at Dien Bien Phu, but as Ike had already disavowed any intent to get involved, the operation was done covertly. Two US pilots lost their lives.

Ho Chi Minh, his general Giap, and all the rest of his fellow commies were responsible for what happened at Dien Bien Phu. Until Giap opened up on the French positions with superior firepower from higher ground, no one in France or the US had any idea about Viet Minh capability. The French had picked the location in order to cut Viet Minh supply lines.
After WWII, the French had insisted on the return of all of their prewar colonial territory, and DeGaulle took a hard line against the countries that had just liberated France, refusing to join NATO, etc. The US didn’t give a crap about Indochina, it only wanted to keep France in the fold.
Total waste of time that was, too, since the result of French mistakes at Dien Bien Phu was to see the hung over French public turn 93% against trying to hang on to Indochina, and the fever pitch against the US and UK get even worse. It’s still a factor in French elections, even among the best-of-the-worst politicians and political parties.
During WWII, Joe Stilwell suggested supporting Mao instead of CKS, an attitude probably influenced by the rocky relationship between Stilwell and CKS, and the great public relations the Maoists had when they received him as a visitor. He didn’t want the US to switch sides, merely support both in their fight against the Japanese. CKS also ran and supplied the Vietnamese resistance to the Japanese occupation.
Truman refuse to give US support for Ho Chi Minh’s takeover. That’ll learn Ho.
“The US didn’t give a crap about Indochina, it only wanted to keep France in the fold.”
That would explain the 60K dead over the next years as we fought there. There is no doubt we pushed the French to fight that war; while they wanted Indochina, they had no interest in fighting to keep it.
The “US pilots” weren’t in the US military; one was so fat he couldn’t get the stick all the way back to take off (his body was recovered in the last ten years).
The French had done a good job of destroying much of the Viet Minh. What ultimately saved Ho and Giap was Chinese involvement in Dien Bien Phu. Of course, the American decision not to use airstrikes against the combined Chinese-Viet Minh force was critical.
