Amendment requires that the rules of engagement [ROE] allow any military service personnel assigned to duty in a designated hostile fire area to have rules of engagement that fully protect their right to proactively defend themselves from hostile actions.
Mr. Paul's views on fiscal matters are just about perfect and if that were all there was to him I would vote for him in a heartbeat. However there are also his libertarian views on defense and security policy and his libertarian "just surrender and get it over with" attitude makes him unfit for the White House.
Having said that I would still pick him over Obama.
