House Speaker Paul Ryan (R-Wis.) visited the Iron Dome defense system Monday during his trip to Israel and made the case for a stronger alliance between the U.S. and the Jewish state.

The Israel Defense Forces tweeted a picture of Ryan alongside his bipartisan delegation of Congressmen at the Iron Dome:

In an interview with the Times of Israel Monday, Ryan lambasted the nuclear deal with Iran, saying that the United States needs to “have a stronger posture with our Iran policy,” saying:

“Where we go from here is to make sure that we don’t backslide on sanctions. That we’re tougher on sanctions. We’re looking at other things in the House. The last thing we want to do is see backsliding.”

Ryan added that “it’s a difference of opinion we have with the [Obama] administration.”

The Speaker, making his first visit to Israel since 2005, said that Iran “is going to make people rue the day they voted for that deal” and that past advocates of the deal are going to regret their support.

The U.S.-Israeli alliance must last, according to Ryan, because Israel is “an oasis of democracy in a tough neighborhood.”

“We have international terrorism that is threatening the civilized world. It’s threatening us. They’re coming at Israel but they’re ultimately coming for us. So we are partners in this war on terror, radical Islamic terrorism,” Ryan said.
