Suicide bombings are used only by societies that value death more than life. That is one of the major differences between western cultures and extreme eastern cultures.
This is a good example of a suicide attack, not of suicide bombing.
I don't really see the difference. Either way, you're killing yourself. You believe your death can achieve something greater than you being alive.

My point was whether it has been done in Western culture or not. The target was not part of the argument. If I suicide bomb a military installation then I suddenly value life more than death?

And besides, I think AFKain is right. It doesn't really matter.
