How can you stop ISIS? It is state sponsored. It is becoming more and more pervasive, with sleeper cells in every nation.
You don't fight ISIS. You walk away and function on a higher level. You start a club where everyone is considered equal, and once it becomes apparent that there are more benefits to being part of a club where everyone is equal, people rush there.
This is why America became a melting pot of cultures and religions. People left oppressive countries to find a place that has greater freedoms and opportunities.
It is in no one's best interest for one individual to be the emperor of the planet. That individual is mortal. He or she rises in power and rules by force, but there is always a backlash to the games.
The United States has resorted to playing oppressive power games, too, but where do you go if the United States is becoming oppressive?
To the international government.
It enables the nations all to function on a higher level, and people may wish to return to their homes, because people like to live within their own culture.
