This is a joke, right? Putin would make mincemeat of that Islamic idiot Erdogan. He is going to close the Bosporus on Putin??? Turkey’s entire economy is dependent on Bosporus shipping. All he wants to do is take his citizens’ attention off of the mess he has created in Turkey.
Turkey is a member of NATO, which operates on the principle of mutual defense.
An attack on a NATO member is considered an attack on all.
