Daesh is just an Arabic acroynym for "Islamic State". ******** like daesh because it doesn't require them to mention Islam, it's their usual politically correct strategy of changing definitions around and playing games to avoid naming the problem.
Islamic State. That's what they want to build, that's the enemy.
From their extreme and radical interpretation of Islam which the vast majority of normal decent Muslims don't subscribe too!
So yes removing Islam from what they are/stand for is both accurate and fair.
