Donald Trump went "On The Record" tonight, telling Greta Van Susteren that the nuclear agreement with Iran is disastrous for the U.S., Israel and the world.

Trump explained that the terrible, incompetent deal will allow Iran to obtain a nuclear weapon, which will lead to nuclear proliferation in the Middle East.

"Let's not play games," Trump said. "You cannot let them have a nuclear weapon."

Why do you think President Obama and Secretary of State Kerry like the deal? Greta asked.

"Maybe they're not bright," Trump said. "There's something wrong with them."

He blasted the 24-day notice before international inspectors can see Iran's nuclear sites, saying that he wouldn't even give them 24 hours.

"Everyone knows Iran is going to cheat," Trump stated.
