Back to Afghanistan
Some of you may have heard of a country called Afghanistan. The US invaded in 2001 because the country was the home base of Al-Qaeda, the group responsible for the terrorist attacks of 9/11. The reason we believe AQ moved there is because Afghanistan was considered a failed state, which made it a haven for illegal activities, including planning terrorist attacks. To me the logical response to such a theory is that we should not let another state fail, least of all a state over which we have control.
