I'm in Israel for the week, and thought I'd have many profound security thoughts. However, the major difference is really just a dogged acceptance that it is necessary to have one armed guard for every group of 15 schoolchildren on a field trip, that walking through metal detectors is necessary at hotels and religious landmarks - and that any temporary ceasefire does not change that necessity.
That is certainly not the mindset in many other parts of the world where terrorist attacks are not so frequent, which I guess is a good thing overall. On the Internet, we are starting to see many enterprises understand that there are no permanent ceasefires but the consumer market is the next frontier.
Which, of course, ties directly to this recent story about understanding new frontiers.
