Huntington's clash-of-civilizations theory posits civilization as the current great problem

Huntington's Clash of Civilizations theory posits Islamic civilization as the current great problem.
He states that under the influence of their religion, Muslims will try to spread their faith all over the world in a violent way. Even though this book came out 1996, Huntington guessed correctly what was going to happen almost 20 years later. As you can see today, the Islamic civilization poses a great threat to the rest of the world.
