Civil libertarians mocked such vigilance, but the message went out that it was now much harder to come to America from the Middle East and in anonymity plan another 9/11. Subsequent terrorist attempts, aimed at targets such as the Brooklyn Bridge and Times Square, either failed or were thwarted before they began.
In wars abroad, radical Islamic jihadists heeded bin Laden’s call to arms and flocked to the Hindu Kush and Anbar Province. The U.S. military and its allies were waiting, and then killed or wounded many thousands of terrorists and insurgents. That indisputable fact is as little remarked upon as it was critical to weakening and discrediting the martial prowess of radical Islam.
