Where did you get this image from? AFAIK it was not violating airspace and even if it was there was no attempted contact with the pilot. This pretty much shows who is supporting and who is fighting the terrorists. One could even see this as an act of war. Here's Putin talking about it. Instead of imminently contacting Russia, they want to contact NATO first. Russia has been violating NATO airspace for yrs w/ no consequences. Blame for Su24 downing lies with Putin & his disregard for intl law. 
Stop supporting Western terrorist coalition. Stop being ignorant and wake up. They will inform nato then they will communicate with Russia with nato. If you are in nato u cannot act like whatever you want.
