Below I have paraphrased troubling dialogue between the Iranian and American Presidents:

Iran’s Rouhani warns Trump ‘don’t play with the lion’s tail’

Iranian President Hassan Rouhani on Sunday cautioned U.S. President Donald Trump about pursuing hostile policies against Tehran as it faces increased pressure and looming sanctions after the decision by the U.S. to withdraw from the Iran nuclear deal.

'War with Iran would be the mother of all wars' he said in a televised speech in Iran's capital, Tehran.

'Do not play with the lion's tail or else you will regret it' Rouhani said. 

Earlier this month, Rouhani hinted that Iran may  block regional oil exports if its own sales are halted. 

The Strait of Hormuz,  between the Persian Gulf and the Gulf of Oman, provides the only sea passage from the Persian Gulf to the open ocean. It is used by Gulf countries who rely on safe passage through the narrow choke point to export their oil and gas, which amounts to around 30% of the world’s oil supply.

'Do not forget that we have maintained the security of this waterway throughout history. We have historically secured the route of oil transit. Do not forget it' he added.
