Chertoff: Layered Defense in Allies’ Interest
Reader Eric asked about the adoption by other nations of the ‘homeland security’ concept. HLSWatch asked Secretary Chertoff in yesterday’s meeting to discuss his recent trip to the Middle East. A member of the media there asked him a question that allies in general ask the U.S.:
The “U.S. fights terrorism overseas to prevent terrorists from performing terrorist acts in the U.S. What’s your comment on these thoughts?
Read: The U.S. advocates a layered global defense against terrorism to keep the threat away from the homeland. This implies to audiences overseas that we’d rather have it out on their homelands. Can’t blame them for assuming the worst, but Chertoff is right to say that a layered defense is the best defense. How that helps allies is in how we define “layers.â€
A layered defense isn’t just about geographic layers though. There are information layers that reveal intentions and enable us and our allies to act before an attack. Financial flows also serve as a layer to create a hurdle that terrorists must cross in organizing an attack. Layers like these are opportunities to complicate the efforts of an adversary and force him into a vulnerable or detectable position.
Allies don’t just benefit from the U.S. pursuing a layered defense. We all do since a true layered defense in the 21st century requires certain basic agreements to be struck among allies. They include the nature of the threat, concepts of success, and acceptable trade-offs. In this sense, any progress the U.S. and Europe make in resolving information sharing for transatlantic flights is mutually beneficial. Of course, if we can’t convince our allies of the mutual benefit, either there isn’t one or we’re not very convincing.
