Now, all the internet service providers that together comprise the core of the internet are American. That’s what Trump means when he says the internet is “ours.” Announcements from American ISPs are thus the most respected and listened-to announcements.
In theory, all President Trump would have to do is have the FCC exercise its regulatory authority over telecommunications infrastructure and arrange to make announcements for the IP addresses owned by Islamic State.
Any traffic intended for Islamic State, on about 95 per cent of the internet, could be redirected to the United States and then “nullrouted” — essentially, dumped into a black hole, perhaps after being analyzed by the NSA or the military. Problem solved.
