Obama Says ISIS Fight Will Be 'a Generational Struggle'

President Barack Obama on Monday said the fight against ISIS would be "a generational struggle." The mission to destroy ISIS "will be difficult, it will take time, [and] there will be setbacks as well as progress," Obama said in a statement after meeting with his top military advisors at the Pentagon. The president said the U.S. has had success preventing large-scale strikes by terrorists but lone-wolf attacks, inspired by the terrorist group, remain hard to detect and prevent. The U.S. would seek to counter ISIS' online propaganda in an effort to limit the terrorist group's ability to recruit young people, he said.
