Rouhlani criticized Trump and warned him not to "play with the lion's tail" and that "war with Iran is the mother of all wars." Instead of having a thick skin, The Donald, of course, fired back with a tweet warning Iran’s ruler not to threaten him again.

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

— Donald J. Trump (@realDonaldTrump) July 23, 2018

"NEVER, EVER THREATEN THE UNITED STATES AGAIN OR YOU WILL SUFFER CONSEQUENCES THE LIKES OF WHICH FEW THROUGHOUT HISTORY HAVE EVER SUFFERED BEFORE."

More broadly, Rouhlani actually didn’t make a real threat, but rather, provided the choices the United States had for a relationship with Iran. "America should know that peace with Iran is the mother of all peace, and war with Iran is the mother of all wars."

Social media, as you might expect, had a field day.

To Iranian President Rouhani: I AM EMAILING ON BEHALF OF THE ESTATE OF NIGERIAN PRINCE ABACHA TUNDE. I WRITE TO REQUEST YOUR ASSISTANCE IN TRANSFERRING MONEY FROM ACCOUNT, WHICH IS REQUIRED IMMEDIATELY DUE TO LEGAL. PLEASE REPLY WITH YOUR BANK DETAILS TO ASSIST THIS. BE CAUTIOUS!

To Iranian President Rouhani: NEVER EVER GONNA GIVE YOU UP. NEVER GONNA LET YOU DOWN. NEVER GONNA RUN AROUND AROUND AND DESERT YOU. NEVER GONNA MAKE YOU CRY. NEVER GONNA SAY GOODBYE. NEVER GONNA TELL A LIE AND HURT YOU.

Whether it’s a threat from Iran and Rouhani, or getting dissed by a celeb, Trump always responds with an angry, unhinged tweet within 24 hours. Yet almost 2 years after Russia attacked our election, Trump still denies it while buddying up to Putin. Easy to see what’s going on.

Trump is trying to distract us from two things:

1) Manafort goes on trial this week.

2) After bending the knee to Putin in Helsinki Trump's asked him to the White House to do it again.

What’s the difference between Hassan Rouhani and Vladimir Putin?

Rouhani is a middle-eastern Muslim who threatened to attack America.

Putin is a white fake Christian who has attacked America and continues to do so.

Yet Trump defends Putin and attacks Rouhani. Why?

Trump is so desperate about his criminal legal problems that he must pander to his white nationalist faux Christian base with anti-Islamic war mongering rhetoric. This is why the GOP’s Vichy collaboration with Trump is so dangerous for the entire world.

In order to distract from Russian attack on American democracy, Trump is looking to start a war with Iran. #MAGA guilty https://t.co/T7RYOl5Uyc

Please dont lie and #shutUpTrump.
Having a president like you is shamful for U.S people.

Luckily, Democrats on the House Foreign Affairs Committee tweeted clarification of the president's message, saying, "DON'T BE DISTRACTED BY ALL CAPS. WE'RE NOT ATTACKING IRAN."

They also urged Trump to hold Russia responsible for interfering in the 2016 U.S. election.
