The left highlights the need to fund healthcare for survivors and argues that the War on Terror was too costly.
A libertarian's take
“Most people alive and old enough to remember can tell you where they were around the time the strikes occurred (hours before the attack, I had walked down a corridor at the Pentagon that one of the planes ripped through) and can recall the ensuing horrifying images and America’s national trauma. If you would ask those same Americans, however, why Osama bin Laden attacked the United States so brutally, most people would not be able to tell you… Any surprise attack by one party on another is usually regarded as treachery, but such strikes rarely occur without a point of contention with the target of the attack…
“Because the U.S. government never admitted that U.S. interventionism in the Middle East motivated bin Laden to attack the United States on 9/11, America still continues to inflame Islamist groups around the world with its attempts to suppress them. Interventionists in the U.S. foreign policy establishment claim that it is naïve to think that radical Islamists will not attack U.S. targets if the American government is not battling them all over the world. What is naïve is believing that you can get rid of terrorism through endless war instead of dealing with the root causes of it.”
