By George Friedman Calls are growing for a no-fly zone over Libya, but a power or coalition of powers willing to enforce one remains elusive. In evaluating such calls, it is useful to remember that in war, Murphy's Law always lurks. What can go wrong will go wrong, in Libya as in Iraq or Afghanistan. Complications to Airstrikes It has been pointed out that a no-fly zone is not an antiseptic act. In order to protect the aircraft enforcing the no-fly zone, one must begin by suppressing enemy air defenses. This in turn poses an intelligence problem. Precisely what are Libyan air defenses and where are they located? It is possible to assert that Libya has no effective air defenses and that an SEAD (suppression of enemy air defenses) attack is therefore unnecessary. But that makes assumptions that cannot be demonstrated without testing, and the test is dangerous.
