Tehran, July 24 (RHC)-- Iranian Foreign Minister Mohammad Javad Zarif has warned U.S. President Donald Trump to be cautious after he threatened the Islamic Republic with incredible hardships in a Tweet.  

Zarif tweeted on Monday: "COLOR US UNIMPRESSED: 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 a millennia & seen the fall of empires, including our own, which lasted more than the life of some countries.  BE CAUTIOUS!" 

Late on Sunday, Trump threatened Iran with what "few throughout history have suffered before." 

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

Earlier on Sunday, President Hassan Rouhani of Iran said the United States should know that peace with Iran will be the mother of all peace while war with the country will be the mother of all wars.  

Under the administration of President Donald Trump, the U.S. has taken an increasingly hostile approach toward Iran.  On May 8, Trump unilaterally withdrew from a 2015 multilateral nuclear deal with Iran over the objections of Europe as well as Russia and China -- the other parties to the deal, which is officially known as the Joint Comprehensive Plan of Action (JCPOA). 

The withdrawal entailed not only the re-imposition of sanctions on Iran but also the so-called secondary sanctions on third countries.  Some of those sanctions will take effect after a 90-day wind-down period ending on August 6, and the rest after a 180-day wind-down period ending on November 4. 

Most recently, the Trump White House has announced that it seeks to supposedly bring Iran's oil sales down to "zero."  Iranian officials have said the U.S. measures equal an "economic war" on Iran. 

On Saturday, Zarif said the Islamic Republic has managed to thwart the Iranophobia plot hatched by Israel and the U.S. through relying on the guidelines of Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei.
