Trump's late-night tweet addressed Iranian President Hassan Rouhani and went into a sharply worded warning in all capital letters of a massive yet unspecified American response if Iran ever threatened the United States again.
The kind of threat that Trump made on Twitter on Sunday could have attracted penalty from the social network for any regular person as Twitter's policy bars users from making threats of violence on its platform.
He said: "The level of corruption and wealth among regime leaders shows that Iran is run by something that resembles the Mafia more than a government".
"We'll see what happens, but we're ready to make a real deal, not the deal that was done by the previous administration, which was a disaster", Trump said on July 24 in a speech to veterans in the USA state of Missouri.
After speaking with European officials about Trump's warnings, International Crisis Group president Rob Malley said diplomats on the continent were not "really taking it seriously". And Iranians have heard them - albeit more civilized ones - for 40 yrs.

"America wants nothing less than [to] destroy Iran" but "Trump can not do a damn thing against Iran", the commander added.
Later Monday morning, national security adviser John Bolton said Trump told him that "if Iran does anything at all to the negative, they will pay a price like few countries have ever paid before". The first round of United States sanctions on Iran goes into effect in August, followed by ones targeting Iran's oil exports in November.
The Mehr news agency, one of the Iranian regime's worldwide voices, reported recently, citing Rouhani's chief of staff Mahmoud Vaezi, that Trump asked "eight times" to meet with Rouhani while the latter attended the United Nations General Assembly in NY past year, but was rebuffed.
"Sadly, after pulling us out of the nuclear deal with Europe and Iran, there doesn't seem to be strategy for how to move forward to fight Iran's activities", she said.
He cited the harsh words between the USA and North Korea that preceded the high profile summit between Trump and North Korean leader Kim Jong Un and denuclearization talks. Israel, Saudi Arabia and the United Arab Emirates in particular feel empowered by the Trump administration's overt hostility toward Iran.
"If anybody's inciting anything, look no further than to Iran", said White House press secretary Sarah Sanders said.
