The Duality of Technology and Int'l Terrorism

Technology is bringing us together...email, cell phone, video phone, sattelite, super sonic air planes etc. etc...now a days people can travel across continents faster than ever before. But the politics of terrorism is making it harder to get the full benefit of faster modes of travels and communications accross coountries. So, could we say one force is centrifugal, one is centripetal..?
Or, there is a better metaphor to capture these rival forces who tend to cancel each other out and perpetuate the status quo..to benefit who??
