Is it entirely inappropriate to ask why terrorists feel it necessary to take over and destroy 'planes in the first place?   I think I'd feel safer in a world where no-one thought it was actually necessary to blow themselves up along with a few hundred other people they have never met and know nothing about.      

For most of my life this has largely been the case. What's changed? The old adage 'Prevention is Better Than a Cure" springs to mind, particularly as the world seems to me to be sick, and getting sicker by the day.

It is also entirely logical that every time a new strategy is developed and publicised for preventing one type of terrorism, it merely invites the development of new, more desperate and despicable acts by the terrorists. These are not people with whom you fight a pitched battle on predetermined ground. After all, which bombing produced the greater 'Shock and Awe' worldwide, Bagdad/Iraq or the Twin Towers?

Are Air Marshalls a diversion, or are we really trying to think our way out of the wrong problem (once again), thereby leaving a door open elsewhere to the terrorists.
