Sometimes it takes some time for the real historical account to surface (especially those associated with a Communist regime and a sympathetic Western news-press). That said, there are those who maintain now, as more records and accounts are surfacing, that Giap was on the outs with the North Vietnam government through much of the US involvement. Any sources or comments on this? Remember that Communist regimes are quick to lionize and slow to discredit. Tet '68 is a good place to start in this type of research and work back from there.
