A spokesman for Iran's armed forces warned U.S. President Donald Trump yesterday against threatening the Islamic Republic and said Iranian forces would teach the United States "new lessons." "It seems the Trump administration only understands swear words, and needs some shocks to understand the new meaning of power in the world," Iranian Armed Forces spokesman Masoud Jazayeri, who is also a Revolutionary Guards commander was quoted as saying by ISNA. "It is time to teach Americans new lessons" he said.

The U.N. atomic agency chief affirmed on Monday Iran's commitment to a 2015 nuclear deal, in a statement that came as President Trump said Tehran was not living up to the "spirit" of the agreement. Trump is a fierce critic of the 2015 accord, which he has called "the worst deal ever", and he is expected to announce that he is "decertifying" Iran's compliance with it.

U.S. officials insist this will not sink the deal itself but open the way for Congress to possibly develop new measures to punish other aspects of Iran's behavior. Congress requires the president to certify Iranian compliance with the deal every 90 days. The next certification date is Oct. 15. Under the law, Congress would then have 60 days to decide whether to reimpose sanctions lifted by the deal.
