I'm looking for a possible thesis for my U. Defense Policy class. The topic could be anything related to U. defense policy, preferably about WMDs.

I'm looking for a possible thesis for my U.S. Defense Policy class. The topic could be anything related to U.S. defense policy, preferably about WMDs. Please give me some ideas on that and make sure it is about defense policy rather than foreign policy. It is going to be a really long paper, so I'm going to need a simple outline about the paper flow. Thanks.
