Turkey opening old sounds - again.
There's a long standing hatred for Armenia and Armenian people by the Turks that Turkey is starting up again, this time placing Turkey (Islamic) and Azerbaijan (Islamic) in a pincer attack on Armenia (Christian) that could very easily turn VERY nasty as Erdogan continues to gather kudos in the Middle East.
This time he's "poking the bear" though by dragging Russia into the conflict. Turkey attempted genocide against the Armenian people that started in 1914 by the Ottomans.
As with most things in the region it's a long and convoluted story intermingled with others where memories are very long and forgiveness almost unknown though it's bloody hard to forgive an attempt of genocide especially when the attacker makes even the mentioning it illegal which is what Erdogan has done though he is not alone.
