It seems that was a genocide in Turkey; 90 or so years ago. However, it dose not make sense to me why the House Foreign Relations Committee had a vote on declaring it a genocide.
Specifically when it was very clear that doing so would piss of a key ally all the while the US is occupying one Turkey's neighboring country.
Can anyone make the case why this vote was a good idea?
