why did nancy powell resign?

my alternative theory (as wendy would say):

Alternative theory #Guha/#Wendy style: amb Powell resigned taking moral responsibility for some gay staffer in US embassy violating sec 377

in other words, the amb did not want to admit that the gay personnel were violating india's penal code and were eligible for jail terms/deportation.
