Dropping bombs on people who very likely have no responsibility for this is what "every element of our national power" sounds ominously as if it might mean. I hope that in this instance Obama, while using the required rhetoric, is too smart to be actually thinking in those terms.

That kind of response would do nothing to reduce the likelihood of this happening again - in fact the reverse.

On the other hand working out a range of sensible precautions and sticking to them does reduce the danger.

In this instance it is very evident that if the people responsible for the safety of travellers had been doing their job the man would never have made it on to the plane.   That is the priority.

Cutting down on all kinds of luggage would make a lot of sense, Expecting people to travel light and buy or rent what they need at the other end makes sense, especially on long distance flights.
