Your (or Professor Pape's) assumption that Suicide Bombing works only applies in the case of 'occupied territory', like Iraq, or the Tamil Tigers in Indonesia. It doesn't translate well to the suicide bombers of 9/11 or the Underground bombers of 7/7. In fact, extrapolating further, it doesn't really apply even to Hamas in Tel Aviv. Sure, blow up a couple buses in the Gaza Strip or West Bank and Israel will gladly leave, but I wouldn't call that a victory. Similarily, while suicide bombing may get US troops out of Iraq, we're certainly not leaving New York or London to al-Qaeda any day soon.

Short summary: the man can collect data, but doesn't seem to be able to interpret shit.
