President Donald Trump launched into a lengthy tirade Sunday against Iran as its leaders continue to slow-walk peace negotiations with Washington as the U.S. war against Iran continues to sink Republicans’ midterm election prospects.“Iran has been playing games with the United States, and the rest of the World, for 47 years (DELAY, DELAY, DELAY!), and then finally hit ‘pay dirt’ when Barack Hussein Obama became President,” Trump wrote on his social media platform Truth Social, referencing the Iran nuclear deal reached in 2015. “He was not only good to them, he was great, actually going to their side, jettisoning Israel, and all other Allies, and giving Iran a major and very powerful new lease on life."The United States and Iran remain in a ceasefire – albeit one that has seen both sides lob attacks on the other – as the two nations continue to negotiate towards an end to the conflict, initiated by Trump in late February, and at the behest, critics increasingly say, of Israel, a claim that’s grown so strong that Trump felt compelled to issue a statement refuting it.While Trump said he expected Iran to respond to the United States’ latest proposal by Friday night, it wouldn’t be until Sunday that Iran reportedly delivered its response to Washington. The delay appears to have frustrated Trump, who on social media, threatened the Middle East nation that it would be “laughing no longer.”“For 47 years the Iranians have been ‘tapping’ us along, keeping us waiting, killing our people with their roadside bombs, destroying protests, and recently wiping out 42,000 innocent, unarmed protestors, and laughing at our now GREAT AGAIN Country,” Trump wrote. “They will be laughing no longer!”
