Suicide Bombers and Conflict
The link is to a Guardian article which talks about research into the background of 462 suicide bombers who have launched attacks in recent years.
It remains, however, that this identified that the bombers themselves were mainly Muslim, but in fact from all religions.
Suicide Bombing contains two main concepts that concern those on the other end of the attacks. The first is that it is an attack that is harder to protect against which is generally aimed at non-combatants. The second is that it involves the attacker consciously deciding to attack in such a way as the attacker him or herself dies.
Kamikaze is the Japanese word for "Suicide" and got into English as a result of the Suicide Air Pilots who flew planes into ships during the second world war.
The big mistake made by the western governments is to fail to look at why people become suicide bombers. It is not because governments are not "tough" on terrorism or terrorists. It is in fact that governments are too tough on innocent people. This has a tendency to wind people up and create divisions. This is what turns people into suicide bombers.
Firm action is needed to deal with actual terror plots. However, if the government went round shooting more and more innocent Brazilians you would find quite quickly a development of a Brazilian type of asymmetric attack of some form.
This is why proportion is crucial in dealing with conflicts. Disproportionate responses increase conflict rather than reducing it.
