It appears it wasn’t that hard once we got a President who actually WANTED to capture him.
Wasn't peculiar that ISIS was nearing world domination in the Mideast and seemingly couldn't be stopped... and then Trump stepped in and demolished ISIS in less than 8 months.
I am convinced Obama wanted nothing to do with harming any Islamist beyond the bare minimum he had to in order to appear convincing that he wasn't one of them.
