Iran responds to President Trump's all-caps threat - with their own all-caps tweet

In response to an all-caps tweet from President Donald Trump, the Prime Minister of Iran has responded with his own cautionary tweet containing capitalized messages.

Here's what Iran said:

Iranian Prime Minister Mohammad Javad Zarif tweeted a response Monday to Trump's threat.

"COLOR US UNIMPRESSED," responded Zarif on his social media account. "The world heard even harsher bluster a few months ago. And Iranians have heard them —albeit more civilized ones—for 40 yrs."

"We’ve been around for millennia & seen fall of empires, incl our own, which lasted more than the life of some countries," he added. "BE CAUTIOUS!"

President Trump had issued a fiery twitter response after the Iranian president made a threat against the United States.

“To Iranian President Rouhani: NEVER, EVER THREATEN THE UNITED STATES AGAIN OR YOU WILL SUFFER CONSEQUENCES THE LIKES OF WHICH FEW THROUGHOUT HISTORY HAVE EVER SUFFERED BEFORE," Trump tweeted Sunday.

“WE ARE NO LONGER A COUNTRY THAT WILL STAND FOR YOUR DEMENTED WORDS OF VIOLENCE & DEATH,” Trump added. “BE CAUTIOUS!”

The statement from President Rouhani that set off Trump was a clear threat to the United States.

“Mr. Trump, don’t play with the lion’s tail, this would only lead to regret," he said to a group of Iranian diplomats.

“America should know that peace with Iran is the mother of all peace, and war with Iran is the mother of all wars,” he added. "You are not in a position to incite the Iranian nation against Iran’s security and interests."

The ruling regime in Iran has been hit in recent months with massive protests by protesters who are tired of the religious war against Israel and lack of basic supplies in the Islamic country. These protests have often been answered by violence.
