WI a US President decided in late 64 or early 65 NOT to send large numbers of ground troops to Vietnam.
1) Does the South Vietnamese administration collapse by 65, 66 68 or later?
2) Is the post war less brutal because the NLF has not destroyed itself (the Tet offensive) hence less like a Northern take over?
3) Assuming it was decided by a Democrat (Kennedy, Johnson, Humphrey or McCormack) what are the political consequences?
