Erdogan is a dangerous lunatic and the EU should impose sanctions upon for his threatening behavior.
Turkey is not a real ally of the West and we should consider revoking their NATO membership. We should continue to increase arms shipments and other military aid to the YPG and covertly do whatever we can to sabotage Turkey's relations with Russia.

The EU also needs to safeguard the refugee deal at all reasonable costs. We can't risk a repeat of the chaos of 2015.
Official sanctions aren't necessary anyway - European tourists are staying away in droves and leading Turkey into a deep recession.
