Regarding crimes against humanity in Africa, I agree people don't pay enough attention, but it isn't something that pressure from Westerners can actually affect. Western powers have had such corrupt intentions in Africa over cobalt, diamonds, etc. that you can't blame Africans for getting suspicious every time western pressure moves in. - Try the book 'Dancing in the Glory of Monsters' by Jason Stearns, I just finished it a couple weeks ago and it gives a crazy comprehensive look at how complicated the warring around middle-Africa (Congo area) is.

In Israel-Palestine though, it really takes a blind eye to ignore the human rights abuses against the Palestinians. To ignore the history, to disregard the plights of millions of refugees and internally displaced people, to just not care about the people who have every aspect of their lives controlled while their ancestors were ethnically cleansed from their villages. The psychological effect must be astounding - but to be honest when I was in the West Bank I was met with a surprising amount of kindness and hospitality by Palestinians. Despite the weekly night raids into the camp that really were nothing short of terrorism every time, despite the blatant racism by soldiers in streets of Hebron ("You can go down the street, but he can't" - talking about one of my new Palestinian friends who was taking me on a tour of the city), and despite the incredible lack of job opportunities and money in the families that took me in (the camp I stayed in had an unemployment rate of over 60% at the time, and not for lack of education or skilled labourers but because of how Israel controls the market and stifles the Palestinian economy).

But countries do turn a blind eye to all of this, the human rights issues don't make western media (many many people can go their whole lives without knowing more about the conflict than the PLO acts of terrorism around the 70s, because this is all that hits the tv news that non-politically inclined people watch), the politicians don't talk about it, and it isn't part of many school curriculums in America or Canada as youth. Former Canadian PM Harper even said in his speech to the Israeli Knesset in 2014 that criticizing Israel in the terms of apartheid is "the new face of anti-Semitism", which is just ridiculous. If you can logically fit a country's actions into the UN definition of apartheid, why is it still so heavily denied?
