DENVER -- "Fire and fury."  "They'll regret it." "Big big trouble."

These are just some of the phrases President Donald Trump has uttered in the past week regarding North Korea -- not to mention tweets.

But how do Trump's comments compare to other presidents? Turns out threatening language has been used by many presidents in the past.

"There can be no peace in the world until the military power of Japan is destroyed." -- President Harry Truman

"It is pointless for them to develop nuclear weapons because if they used them it would be the end of their country." -- President Bill Clinton

"Saddam Hussein and his sons must leave Iraq within 48 hours." -- President George W Bush.

But what makes Trump different, according to experts, is the apparent off-the-cuff nature of the remarks.

Traditionally, "war threats" are done after consulting a president's National Security team.

"President's words always have meaning," said professor Norman Provizer, who studies presidential history at Metro State University of Denver.

"Presidents have to always recognize the consequences of situations and that is where improvisation get's problematic."

Some military experts -- including Congressman Mike Coffman -- have praised the president's improvised nature with this, calling it a tactic.

"It's just a dangerous tactic when the stakes are very high," Provizer said.
