The following in an edited version of a paper I presented two weeks ago in a debate on the topic "When should the US use force abroad and what lessons should we learn from America's use of force in Iraq and how should those lessons inform decisions on future military missions abroad?"

There are really two questions here – when is the use of force justified in the context of the key word "abroad" and what have Americans learned regarding overseas interventions from the Iraq experience. As a foreign policy adviser for Ron Paul in 2008 and 2012, I lean in a non-interventionist direction, but that is at least somewhat due to that fact that recent interventions have not worked very well and have in fact increased the number of enemies rather than reduce them while also killing nearly 7,500 American soldiers and more than a million inhabitants of the countries Washington has become entangled with. One might also reasonably argue based on post 9/11 developments that destabilizing or attacking other countries consistently makes bad situations worse and has a tendency to allow problems to metastasize. This is sometimes referred to as blowback.
