" I wanted a president that actually knew about foreign policy and terrorism."

Are you familiar with the Rape of Libya?  Probably not something they cover in your high school civics classes.  Whenever you get to upper level political science you are almost certain to cover US foreign policy.  

A basic summary is that NATO turned Africa's wealthiest country into Africa's poorest.  A wealthy, modern, secular country is now an Islamic fundamentalist hell.  Hillary Clinton was the primary architect of the "regime change" policy in Libya and was instrumental in getting the no-fly zone some international backing.  

Then her emails were exposed, and we found out the real reason we went into Libya (and Clinton knew all along).  French colonialism and Western imperialism.  Gold and oil.  By all accounts, Libya was a complete and total disaster.

Did Clinton learn anything?  Of course not.  She still advocated "regime-change" in Syria despite everything that happened in Libya.
