“In terms of any additional steps we take, it’s going to be based number one on the facts on the ground, number two what’s in the interest of the American people and our national security,” Obama said. “As president of the United States, I am going to make those decisions based on the best evidence and after careful consultation. Because when we rush into things, when we leap before we look, then not only do we pay a price, but we often also see unintended consequences on the ground. It’s important for us to do it right and that’s exactly what we’re doing right now.”
