"Duck Dynasty" star Phil Robertson is against the nuclear deal that US President Barack Obama has forged with Iran, saying he is not going to sit idly by and let this happen.

In joining the "Stop the Iran Deal" rally held outside the US Capitol on Wednesday, the outspoken Robertson patriarch said he mistrusts the Iranian regime but loves Israel, because that is the birthplace of the Bible.

"I don't do deals with individuals whoever they are, when they're hollering at the top of their lungs when I walk out the place where we're doing the deal, and they're saying: 'Death to you! We're going to kill you,'" he told CNS News. "That's the last bunch you want to have nuclear weapons."

"Israel, the most faithful ally that we have," he continued. "You know why I love Israel? They wrote the Bible. That's why I love them."

Phil proved his knowledge of history and the Bible when he traced the ancestry of Jesus Christ, and he strongly encouraged Christians not to put Jesus' people and descendants in harm's way.

"When God chose to become flesh 2,015 years ago—your calendar dates that event, God becoming flesh—you know what kind of flesh he became? Jewish flesh," he said. "Theirs are the patriarchs—Abraham, Issac, Jacob. They wrote the Bible, for crying out loud. Therefore, you never, ever want to put them in unnecessary danger, which this deal will do."

Earlier, Phil got into a lot of trouble during his interview with GQ magazine because of his unrelenting views against homosexuality.

"Everything is blurred on what's right and what's wrong," he said. "Sin becomes fine. Start with homosexual behavior and just morph out from there. Bestiality, sleeping around with this woman and that woman and that woman and those men... Don't deceive yourself. It's not right."

Phil even got suspended from the family reality show "Duck Dynasty," but the other Robertsons firmly stood by his side and he was eventually allowed back on the show.
