You've got 7 years in the army, and a political science degree? Although "conflict mediation"? Did you actually look up how many jobs there were for that? Also, what was your focus for political science? Legal Studies, public administration...?
You need to look into a job at a law firm as a paralegal, or into police/private sector security.
What have you been looking for that you haven't been able to find anything? What have you been applying for?
Also, remember that temp agencies can be a big help.
7 years in the Marines. My focus of study was international affairs. I would like to work for the DOS, NSA, DHS or something like that in the field of security studies, development, nuclear development.
