Everything about this is weird. See the news article where Erdogan is blaming a former Turkish cleric and associate living in PA.
The full military clearly wasn't behnd it, as there were neither strategies nor tactics.Too many people died to think Erdogan was behind it, and a lot of military are now under arrest. Suggesting Erdogan could maintain plausible deniability given these conditions strains reason.
It seems that religion is the reason for this treason.
