....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 United States imposed sanctions on senior Iranian officials, including Supreme Leader Ayatollah Ali Khamenei, on Monday. US sanctions on Foreign Minister Mohammad Javad Zarif are expected later this week.
Tensions between the two long-time foes have escalated over the last month, when Washington blamed Tehran for attacks on two oil tankers and Iran downed a US surveillance drone. Tehran has denied responsibility for the tanker attacks and has said the US drone was flying in Iranian airspace.
Trump said he called off a strike on Iran last week in retaliation for the drone incident, after he decided at the last minute it would kill too many people.
