The risk with President Obama’s new strategy to destroy the Islamic State is that he could start an open-ended conflict, said Carnegie’s Frederic Wehrey on CNN. There was no clear sense from Obama’s speech that he was capable of reaching an end state where there would be a political solution, Wehrey argued. “The real challenge is ensuring that this group does not reemerge. We know these types of groups are incredibly resilient.”
