Asking for help from both Truman and Eisenhower administrations, he and his movement were callously ignored by our state department, and France was returned to its prewar oppressive ways in Viet Nam.
Discouraged by this, Ho Chi Minh approached the communists for help with his movement.
The rest I believe you know about.
Sigh. Our country is not perfect by any means. But there are some things so egregious that they constitute a black mark on our national conscience.
This decision you reference seems to be less a case of betrayal, than of “Realpolitik” (a term I both deplore and yet recognize the mechanism of...the case of doing what is easy, not what is right)
Given what we know about DeGaulle and France at that time, and the haranging that likely went on from their quarter, we may have simply decided it was easier to let the French continue with their colonialism and let the chips fall where they may.
To our later detriment, of course.
