Press TV - The administration of US President Donald Trump is �tarnishing� itself by adopting foolish decisions including travel ban for Iranians and five other countries, says an author.

Authorities detained an Iranian cancer researcher and his family who traveled to the United States�on a valid visa on Tuesday at Boston�s Logan international airport. Mohsen Dehnavi and his family were put on a return flight.

John Steppling told Press TV that the deportation of the researcher was �a shameful incident� and it showed�the current US administration was happy with waging an economic, military, and political war against Iran, the Middle East and the Arab world in general.

�They (American authorities) are not going to be put off by any ideas of embarrassment or the moral bankruptcy in this, but of course it�s shameful and there�s people that are acutely aware of the clumsiness and the vulgarity of the Trump administration,� Steppling said on Wednesday.

The response to the�travel ban�is not going to change policy, because �these are people who are bigoted, xenophobic and imperialist and they see nothing wrong with that and they are proud of it," he said.

�The influence of the Pentagon is huge� and �the Pentagon is currently targeting Syria and then Iran and participating in the near genocide in Yemen,��Steppling said.

The Trump administration called for a travel ban on citizens from six Muslim countries, namely Iran, Libya, Somalia, Sudan, Syria and Yemen, but it was challenged. However, the US Supreme Court recently reinstated the controversial ban with some minor changes.
