The US is normally the country that bombs the middle east but in Aleppo it was almost exclusively Russia and the Assad regime that did the bombings. Saudi Arabia (and to a lesser extent Turkey) were the ones who sponsored ISIS. The US for once actually sponsored the relatively good guys in the conflict by backing the AANES ("Rojava").
This is not to say that the US had any moral reasons to choose the AANES. It was strictly geopolitics but even a broken clock is right twice a day.
In a quota that uses integers and puts 100 as the average, a lot of people will be exactly average. Therefore it is incorrect to say that 50% is below average. It's probably somewhere between 48% and 49%.
