Yeah, and as i said before i wondered how tribunals like the one in "Encounter at Farpoint" could still exist in 2079. After all the Vulcans at this point were already on Earth for around 16 years.
And the Vulcans had a pretty solid non-interference policy. They'd offer guidance and support, but wouldn't actually take over or impose order. I imagine it'd be something more like US military's efforts to help the Iraqis and Afghans set up new governments of their own, which has been a slow and imperfect process at best and had numerous setbacks over the years. And that's just in a couple of countries. Helping the entire planet recover would probably take decades, and some regions would take longer to recover than others.
