North Africa countries have adopted an overwhelmingly legalistic approach to returning foreign fighters. In line with the 2014 UNSC Resolution 2178, which required countries to take steps to address the foreign fighter phenomenon, most countries (with the exception of Libya) now have legal frameworks for prosecuting returning foreign fighters, for the most part for having joined a terrorist group abroad. Therefore, returning foreign fighters who are detected at official ports of entry will face arrest.

Alongside claims for justification from the Trump administration, similar rhetoric featured in statements from French and British leaders. French President Emmanuel Macron claimed there was no doubt Syria was responsible for a chemical attack on civilians, in gross violation of international law.
