US NATO attack on Syria

The US government are trying to convince the world and themselves that the atrocities committed against civilians in Syria are the reasons for which they want to attack the country. I accept that the use of chemical weapons is abhorrent and immoral but the US needs to find a better way to get us to accept that their involvement is because they want to preserve international rule of law. How about they get their ally Turkey to observe international law by withdrawing from occupied north of Cyprus? Not only do they not do this but they continue to arm the Turkish army to perpetuate the illegal occupation??
