Few things I didn't get/Your opinions on some things

Who was the leader of the military faction, that small guy with (originally) two robot bodyguards with glowing eyes?

Was the professor really good and determined on bettering the situation in the desert or was he just a power-grabbing bastard like Sunabozu claimed?

If both Sunabozu and Junko switched sides to military, do you think he finally got to bang her?

What do you think happened to the rest of the world, outside Kanto desert?
