The fight against ISIS is "a third world war by other means," Jordan's King Abdullah II told CBS News' Charlie Rose during an interview on Friday morning.



The king is currently in Washington and is due to meet with U.S. President Barack Obama later on Friday.



"This is a Muslim problem," Abdullah said, referring to the challenge posed by the Islamic State. "We need to take ownership of this. We need to stand up and say what is right and what is wrong."



The king added that Arab and Muslim leaders around the world were beginning to work together to defeat ISIS, though he was unwilling to give details.



"This is a war inside of Islam," he said. "So we have to own up to it. We have to take the lead. And we have to start fighting back. And all of us have to make that decision and stand up to the plate and take our responsibilities."



Despite the threat of ISIS, the king still considers the Israeli-Palestinian conflict the core issue in the Middle East.



"You know, whether it's true or not, that argument is still being used by the extremists," he said. "And countries around the world realize that they have to solve the problem for their benefit."
