Each and every ISP that has any interconnect with another country would need to be mandated to participate. A cyber-threat type of 24/7 monitoring center with a palatable mix of representatives of each ISP involved, government security, private security entities, etc. would use an established set of protocols to identify external threats. Companies like Symantec already have such centers. Once identified, and that threat is out of US jurisdiction, said IP address(es) are identified and distributed amongst the participating ISP routers and blocked. Shut 'em down, immediately. And just like getting yourself on an RBL, have a set of protocols in place to follow to get off the blocking list.
