Because it is bordering on Islamic extremism, military coup, and involved in a bloody multi-decade civil war.
None of that. I dislike Erdogan and his Islamic rhetoric, but bordering on Islamic extremism? Not really.

Military coups have occured in the past, but it's unlikely that it'll happen again. Who knows, though? This multi-decade civil war you're talking about concerns the Kurds, I assume. I think you're making it larger than the way it is in reality.
