Thin-skinned bully Donald Trump melts down after and promises total “obliteration” of Iran after President Hassan Rouhani mocked him as “mentally retarded.”

Trump tweeted: “….Iran’s very ignorant and insulting statement, put out today, only shows that they do not understand reality. Any attack by Iran on anything American will be met with great and overwhelming force. In some areas, overwhelming will mean obliteration. No more John Kerry & Obama!”

The meltdown came after Rouhani clapped back at the additional sanctions Trump imposed on Monday. The Foreign Ministry spokesman tweeted that the sanctions against Iran’s leaders means the “permanent closure of diplomacy.”

By the way, Trump said he imposed sanctions against Ayatollah Khomeini, who has been dead since 1989. He meant Ayatollah Ali Khamenei.
