On September 11, 2011, a solemn memorial service will take place at Ground Zero on the tenth anniversary of that fateful day when 3,000 innocent Americans were killed by an attack on the United States by radical Islamists. It will remind us that although Osama bin Laden was killed by American Navy Seals, the war against radical Islam continues. Indeed, it has simply entered a new phase, the nature of which will be determined by the outcome of the Arab Spring. As in memorial services in previous years, the names of the dead will be read by their relatives, who still suffer their losses. And it is important that we should be reminded of that day, which destroyed our delusion that the fall of the Berlin Wall would usher in a new era of world peace and happiness. Instead, we now face, for the indefinite future, a global war declared by radical Islam. Several years ago, a PBS Frontline film showed, for the first time, people leaping out of the windows of the World Trade Center, hurtling their bodies to sudden death.
