Strengthening the U.S.-Israel relationship in a new world and a homeland facing new challenges of global terror is more important than ever, Democratic presidential candidate Hillary Clinton said on Monday.

“The alliance between Israel and the U.S. in now more important than ever in this time of terrorism and turmoil. We have to take our alliance to a new level. That has to be in our own national interest,” Hillary said during a presidential forum hosted by the Jewish Federation of Greater Des Moines in Iowa on Monday. “Israel needs a strong America by its side, and America needs a strong and secure Israel by our side — to have an Israel that remains a bastion of stability and a core ally in a region of chaos.”

In her opening remarks, the Democratic presidential hopeful condemned the recent wave of terror attacks in Israel. But more broadly, she said, Israel and the US need to work together on the war against ISIS, the threat of a nuclear-armed Iran and the delegitimization of Israel.

On the Iran nuclear deal, Hillary said it’s not just important to say ‘yes’ to the nuclear deal but also make sure it is enforced and Iran’s sponsor of terrorism is confronted aggressively. “How we handle enforcement in these early months will set the tone for years to come, so we have to get it right,” she stressed. “There must be consequences to snap sanctions back into place. And we have to make sure that Iran knows that if they try to develop or acquire nuclear weapons, the United States will stop them. We will act decisively.”
