The PM reckons the web and Twitter would have made the murder of millions of Rwandans in the 1990s impossible, according to The Guardian.
The online spread of information about the current unrest in Iran indicated a change "more tumultuous than any previous economic or social revolution", Gordon Brown said.
"This week's events in Iran are a reminder of the way that people are using new technology to come together in new ways to make their views known," he said.
Then, launching into utopian hyperbole, he mused: "You cannot have Rwanda again because information would come out far more quickly about what is actually going on and the public opinion would grow to the point where action would need to be taken."
We'd like to see him try Twittering that to people in Sudan, or Northern Sri Lanka, or Somalia. ®
