US going to ‘great lengths’ to inflict damage on Iranian exports out of the region

The Australian Columnist Tom Switzer says the US is going to “great lengths” to inflict damage on Iranian exports out of the region. Mr Switzer told News24 host Chris Kenny that the US air campaign “clearly failed” to make Iran conform to American expectations. “So, Trump’s calculation now is to try to choke the regime economically while he imposes the naval blockade.”
