The reason the Israeli-Palestinian confict is so present in people's minds is because terrorism works. The aims of terrorism is to bring your cause to the forefront and for people to engage in debate over it. Eventually some nation will do something stupid then people start to feel sorry for the terrorists and begin to support their cause. It happens over and over again. No one gives a sh*t about oppressed peoples that don't engage in violence. Often you have to bomb a western nation before people sit up and take notice of your cause.
Your stats are really depressing eagleseven. There are so many wars and genocides that have taken place (and are taking place) that are all but invisible in the eyes of the west. Its as if they never happened... And it seems to be especially hard on black Africans, whose lives are seen as the most worthless and expendable - racism is definitely an element. The worst thing is a lot of these conflicts are indirectly caused by western imperialism in the first place.
(And BTW you notice that the statistics are for 'the Arab-Israeli confict'. That is including the 1948, 1956, 1967, 1973 wars between Israel and various Arab nations, which weren't even about the Palestinians' rights (as the conflict is viewed today) and they make up most of the death toll. In reality, the current Israeli-Palestinian conflict is even lower on that list)
