The Trump travel ban actions include two executive orders for restrictions on citizens of seven (first executive order) or six (second executive order) Muslim-majority countries. A third action, done by presidential proclamation, restricts entry to the U.S. by citizens from eight countries, six of which are predominantly Muslim. During and after his election campaign Trump proposed establishing safe zones in Syria as an alternative to Syrian refugees' immigration to the US. In the past, "safe zones" have been interpreted as establishing, among other things, no-fly zones over Syria. During the Obama administration Turkey encouraged the U.S. to establish safe zones; the Obama administration was concerned about the potential for pulling the U.S. into a war with Russia. In the first few weeks of Trump's presidency, Turkey renewed its call for safe zones and proposed a new plan for them. The Trump administration spoke with several other Sunni Arab States regarding safe zones, and Russia has asked for clarification regarding any Trump administration plan regarding safe zones.
