I'm American.
I believe 9/11 was a set-up, so I don't care about it at all.
When Haiti got hit with a tsunami, I almost laugh. It turned to anger when they started refusing the food we were giving them because it wasn't good enough. I didn't care.
New Zealand gets hit with an earthquake and the only thing I care about is the architecture, nothing more.
Now with Japan, I didn't care at first. The difference is the death toll and our relationship with the country. The video footage on the internet is terrible, from the destruction to the screams of the dying which will haunt my mind for many nights to come. Their reactors are close to meltdown, which would ruin vast areas of Japan for hundreds of years, and then a volcano erupts killing even more people?
This country is getting hit so hard that they have run out of body-bags and coffins for their dead. Think about that.
This is probably a first but, yeah, I care.
