Last week, the Iranian government shoot a US drone, the American President Donald Trump said he planned to have retaliation attack but called off the attacks because it would have killed too many people.
The Irianian government described the White House plan for retaliatation attacks as mentally retarded. Mr Trump replied via twitter about Irans comments
"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!".
