I was irritated during the Massacre in Rwanda when it was happening. The media simply reported it in real-time as "oh well, glad we're not them". Change the time ten years, a major Tsunami happens, and we have Clinton and Both Bush's pleading for public support, religious and secular groups pouring money and aid into the region (as well as billions of tax dollars, which is why I opted not to volunteer any funding).
Two situations that are as similar as they are different.
Rwanda - political massacre, UN and westerners left the area before it happened. Nobody cared.
Indian Ocean - natural disaster, everyone on the planet uncharacteristically gives a s**t.
Rwanda was located in a remote place with no vested interest to the Western Economy. So, they just let it happen, the governments, the media, UN and NATO. The Tsunami killed 1/10 of the people, but it was in a region that is bursting with American and European investment. You can bet that most of the money that was transferred over there DID NOT go to the poorest and most destitute. CASE in POINT - Katrina
