The Trump administration announced Friday that it is adding six new countries to the existing travel ban, joining the seven already on the list. The administration's rationale for the ban is that conditions in those countries, especially the level of terrorism, raised the risk of allowing their citizens into the U.S. to an unacceptable level. But if the administration is correct about the risks posed from the countries on the newly expanded list, why does it continue to allow the U.S. government and companies to sell weapons to more than half of them? During the Trump administration alone, the U.S. has sold Libya, Yemen, Eritrea, Kyrgyzstan, Myanmar, Nigeria and Tanzania (the last five of which are new additions to the travel ban) everything from handguns and automatic weapons to light attack aircraft. Since 2002 the U.S. has sold roughly $409 million worth of these weapons to 10 of these 13 nations despite their troubled political systems, poor human rights records, high levels of corruption and their participation in a range of conflicts. In these places, U.S. arms have not brought stability, much less peace. Instead, in many cases they have led to increased homicide rates and fed state-sponsored violence, and may have exacerbated rather than ameliorated terrorism and civil conflicts. The U.S., for instance, has delivered millions of dollars in weapons to Nigeria since Trump took office and the country is notorious for losing these weapons to Boko Haram - the exact group the weapons are being sold to fight.
