Retired Air Force Col. James Waurishuk said Tuesday he’s not concerned that Iran will respond with military action to recent tweets by President Donald Trump.

“Iran has to show its restraint, and it has to show it’s responsible if it wants to play on the world stage as a regional or world leader,” Waurishuk told host Laura Ingraham on “The Laura Ingraham Show.” “It has to take the tough calls from a country that’s serious about its role, and we’ll see where it goes. I don’t believe this is going to develop into anything other than some rhetoric.”

Trump warned Iranian President Hassan Rouhani (pictured above left) in a tweet Monday that he would suffer severe consequences ,the likes of which few throughout history have felt, if he threatened the United States again. Many in the liberal mainstream media responded by claiming Trump was stoking tensions, with some talking heads going so far as to speculate what a war with Iran would be like.

“He hasn’t fired any shots, he hasn’t done anything from the standpoint of military action against Iran,” said Waurishuk, who formerly served as special operations intelligence officer on the National Security Council. “So, to me, it doesn’t give Iran a reason to do something militarily. If Rouhani or whoever in Iran wants to respond with tweets, that’s fine, and that’s all we’ve been seeing, and I think that’s all it will come to. ”

Iran has only responded with statements and tweets of their own. Iranian Foreign Minister Javad Zarif tweeted that they were unimpressed, while warning the United States to be cautious. Foreign Ministry spokesman Bahram Qassemi warned the United States would be met with equal countermeasures if it blocked Iranian oil exports.

Waurishuk took issue with some pundits attacking the president for not having a national security background, noting that former presidents Barack Obama and Bill Clinton also lacked such experience.

“President Trump has surrounded himself with, I think, a pretty good cadre of national security experts, from John Bolton to Mike Pompeo and Gen. Mattis,” Waurishuk said. “So I think he is well-prepared to deal with any national security issues that come to mind.”

White House press secretary Sarah Huckabee Sanders told reporters on Monday that the president had been tough against the Iranian government since his first day. She added that he was showing that he won’t tolerate threats against the United States or nuclear proliferation.
