IRI is lucky Trump is focused on starting trade wars with Canda, Mexico, China and Europe (and many other countries)
he has also removed the warmongers that he appointed to his first cabinet (Pompeo, Bolton, Haley)
he clearly doesn't want war with Iran and likely perceives Iran to be weak enough to agree to diplomacy instead. but can't exclude the possibility that Trump will launch some risky military plays if he perceives the risk to be low e.g., another Operation Martyr Soleimani that doesn't kill any Americans and destroys 4-5 tents in Iraq.
