(CNN) —  

Former White House communications director Anthony Scaramucci said President Donald Trump’s remarks that the United States is “locked and loaded” in response to an attack on Saudi Arabian oil fields are a “predictable level of irrationality from him.”

In an interview on CNN’s “New Day” Monday, Scaramucci said Trump’s words are an “irony” and will have “less and less of an impact.”

“You would want somebody in that position that had way more temperance, you would want somebody in that position who understood as the guardian of democracy and as a beacon of hope for people,” Scaramucci, a former Trump administration employee and public supporter turned critic, said. “Our grandfathers through 75 years of good policy enabled the United States as the largest military in the world. And so talking like that from that position in many ways is anti-American.”

On Saturday, coordinated strikes on Saudi Arabian oil facilities disrupted 5% of the daily global oil supply. Trump tweeted on Sunday that the US has “reason to believe that we know” who is responsible for the attack and the country is “locked and loaded depending on verification” following the strike.

“Saudi Arabia oil supply was attacked. There is reason to believe that we know the culprit, are locked and loaded depending on verification, but are waiting to hear from the Kingdom as to who they believe was the cause of this attack, and under what terms we would proceed!” Trump wrote.

Trump’s tweet, which appeared to raise the specter of a US military response, served to ratchet up tensions in a region already on edge, though the vice president’s chief of staff Marc Short told reporters Monday morning that the President’s claim the US is “locked and loaded” may not refer to military action.

Scaramucci said on Monday that while the attacks on the oil fields are a “serious situation,” he thinks the impact it will have on the economy will be “slight.”

“I think 5% of the oil, it’s a lot but I do think the President is making a smart decision to release strategic petroleum reserves if necessary. My guess is it won’t be necessary. It’s just a notion that that’s going to happen will calm down the oil markets. I think what’s more concerning is why those areas, why those refineries are not more protected. You have to be worried about that because it’ll be future attacks.”
