ISIS took control of Libya after American intervention

Trump pointed out that ISIS took control of the oil from Libya. This is the same ISIS that Trump was able to take out in partnership with King Salman almost instantaneously. It's almost as if Clinton, Obama, and Bush did not want ISIS to be dismantled and they empowered them.

If the deep state was in near full control since at least Bush Senior, then which one of these wars was actually justified?
