This is an issue for states and localities to legislate and enforce. I don't want it under Federal jurisdiction.

How do states and localities enforce laws against child porn on the internet which crosses all state and national boundaries? Or are we China if we block overseas kiddie porn sites?

If someone in a given US state or locality is distributing child porn, prosecute them under the regional laws there. This could be done more efficiently and effectively than the Federal Govt.

If the material is coming from overseas, local providers could block content from those domains.

Still, the best option is the filter content at the most local level—i.e., by blocking material you don't wish to see on your own computer. There are numerous softwares out there for doing this.
