How State Sponsors Gave Al Queda Global Reach

The Belmont Club shows the importance of safe enclaves for terrorists:

His last paragraph is crucial to understanding why the defeat of the Taliban in Afghanistan and the toppling of Saddam Hussein may have cripped global terrorism so badly. Without the infrastrastructure of a state sponsor, terrorism is limited to cells of about 100 members in size in order to maintain security. In the context of the current campaign in Iraq, the strategic importance of places like Falluja or "holy places" is that their enclave nature allows terrorists to grow out their networks to a larger and more potent size. Without those sanctuaries, they would be small, clandestine hunted bands. The argument that dismantling terrorist enclaves makes "America less safe than it should be in a dangerous world" inverts the logic. It is allowing the growth of terrorist enclaves that puts everyone at risk in an otherwise safe world.
