What we have found in Afghanistan confirms that, far from ending there, our war against terror is only beginning. Most of the 19 men who hijacked planes on September the 11th were trained in Afghanistan's camps, and so were tens of thousands of others. Thousands of dangerous killers, schooled in the methods of murder, often supported by outlaw regimes, are now spread throughout the world like ticking time bombs, set to go off without warning.
