McCain. More clueless than I imagined

As Islamic State forces push forward in Syria and Iraq, Senator John McCain assesses it like this:

“We now have the largest, richest, most powerful caliphate and base for terrorism in history,” McCain continued. “They now encompass an area larger than the state of Indiana and they are dedicated to attacking the United States of America.”

It seems Sen. McCain is unfamiliar with the history of the Ottoman Empire. He also seems unaware of Islam's record of conquest in North Africa and Europe.
