First, to put the current terrorist threat in reasonable perspective to ongoing daily life risks, the terrorist threat is different but not of great significance. Most of the anxiety has to do with the news media hype. There have been several commercial passenger aircraft crashes this year due to mechanical problems, pilot error and weather. These crashes rate one to two day exposure on the news and are then replaced by other breaking news. When the news media talks about an aircraft downed by terrorists, it has to go back five or ten years generally to a crash in Scotland.
Second, opting for the benefits (promises, providing other conditions are met) of life after death, generally via suicide, the driving force is usually despair, fear or some other major negative life situation. The only persons generally opting voluntarily for death do so for religious and/or patriotic or to protect a loved one. Those that opt for death on religious grounds generally do so because of strong pressure from a highly regarded individual or group. An example of the former would be the Jim Jones group suicide in South America 15 or 20 years ago. An example of the latter would be the suicide bombers in Afghanistan.
Third, I think the major cause for concern in the present situation regarding terrorists, arises from our not being accustomed to such a threat. We do not get overly concerned about the 30,000 to 40,000 people killed in automobile accidents each year, are the large number of deaths due directly or indirectly to alcohol or tobacco. Given time, we will find the right level of action to put the terrorist danger in proper perspective. It is probably fortunate that we have serious doubts regarding the benefits of life after death, otherwise the suicide rate would be overwhelming.
