I'm not displeased that he is dead. It is IMHO, a good thing but I don't think it is a time to celebrate or crow. It needed to be done, but you don't celebrate taking out the trash.

The bad news is that retaliation is likely. The good news is that much of this retaliation is likely to be small and unplanned opportunistic attacks and mostly overseas. Any planned attacks will tend to have had their schedules advanced. This is good because a rushed attack is more likely to be sloppily executed and easier to catch.

The key to terrorism is that it doesn't disrupt your life as much as it causes you to disrupt your own life. Either way, if it disrupts your life it has done its intended job. So, be observant but carry on.
