The USA would have to rewire the entire nation, not just take control of tier 1 providers. Since the current system does not have sub sections that would be required under a SOPA network. You’d have to introduce an entire firewall system, replace all existing systems. Yet your country does not even have good internet technology, and is far behind places such as Japan and South Korea in networking. It’s just not going to happen, and anyway SOPA does not allow for blocking of IP addresses, only domain names.
