Are all opponents of the recently brokered Iran nuclear deal the same people who supported the 2003 Iraq Invasion? Not at all, according to this group of Iraq veterans. Veterans Against the Deal, a nonprofit founded last month, is launching a multi-million dollar effort to oppose the United States’ support of the nuclear deal on the grounds that it will actually lead to more war.

Veterans Against the Deal is using a national advertisement campaign to give military veterans a voice in an issue that hits particularly close to home. The ad campaign will include commercials in states whose Congressmen are undecided on the Iran deal. Congress will vote on the deal in September.

“We are going to challenge those people who are on the fence,” Veterans Against the Deal executive director and Iraq veteran Michael Pregent said. “Our main argument is that veterans know Iran better than Washington, D.C., does. You’ve got a lot of veterans out there who are pretty upset about this, so we are looking to capture their voices and make sure they are heard.”

The nonprofit’s campaign explores the immediate impact of giving more economic freedom to a state that incubates terrorism and religious fundamentalism.

If the deal goes through, Iran will receive $100 billion of frozen assets. In this Veterans Against the Deal video, Sgt. Robert Bartlett worries how Iran will use that money.

Pregent told BloombergView that veterans from across the political spectrum are uniting against the deal, including many who voted for President Obama.

“These guys want to be heard. They know this enemy. They have a constant reminder of permanent loss because of Iran,” Pregent said. “If someone said to me, ‘Aren’t you exploiting these veterans and families?’ I would say, ‘No, aren’t you ignoring these veterans and families?’”
