IS taking more

When Islamic State conquered the ancient city of Mosul, Iraq, their videos trumpeted destruction of important works of art. Now they have conquered the city of Palmyra, Syria, and again they destroy. This time it's an ancient temple that's blown up.

They control over half of Syria's territory, and now have also taken the city of Ramadi, Iraq, which has surprised American advisors.

They have so much money that they're planning to buy a nuclear bomb. Pres. Obama promises to send ground troops if that happens.
