Under the principle of "do unto others before they do unto you," this sets the BRICS to be protected when takeing the root servers that cover the rest of the Interent. Given the capabilities already demonstrated by Russia and China, this isn't at all far fetched here. Harder than back in the '90's, and I was looking at what would be required technically, due to increased capability (system speed) and improved resilience of BIND, but not impossible. Offense usually trumps defense most of the time especially when defense has to be perfect while offensive only has to be successful once or a few times.
"As the stars went out, one by one" comes to mind here.
