Reacting to US President Donald Trump's criticism, Iranian President Masoud Pezeshkian said that Tehran won't bow to any bully. "He (Trump) thinks he can come here, chant slogans...and scare us. For us, martyrdom is far sweeter than dying in bed," Pezeshkian added. Earlier, Trump, speaking at GCC summit, said Iran must stop sponsoring terror and halt its bloody proxy wars.
