7/7 attack was a game-changer in Britain

After four home-grown suicide bombers killed 52 London commuters on July 7, 2005, British prime minister Tony Blair vowed that Britain would stop at nothing to defeat terrorism.

“Let no one be in any doubt,” he said. “The rules of the game are changing.”

Since the September 11 attacks in the US four years earlier, Britain had made its anti-terrorism powers among the toughest in the Western world. Now they became tougher still.
