On Monday's broadcast of "CNN News Central," White House National Security Communications Adviser John Kirby said that Iran's attack was "escalatory" and "a huge step in the wrong direction." But "just because Iran conducted this unprecedented attack, which we and our Israeli partners and other partners thwarted, doesn't mean that we should just accept a constant, rising escalation in the region. The president's not going to accept that. He wants to see things de-escalate, and everything we're going to do from this point forward is going to be designed to continue to try to reach that outcome." Kirby also stated that the decision on how to respond is up to Israel.
