Its true that using the term &quot;Levant&quot; may seem outdated. However, if you recall ISIS&#x27; (or Daesh&#x27;s) call to arms, it was to erase borders - and specifically the ones delineated in the secret WWI agreement known as Sykes-Picot. Back then, the goal was to carve up the Levant between France and the UK. So, using ISIL is in reference to their stated mission. Maybe more reason to not use any IS or IS derivative...
