Didn't quite follow the Turkish President on this one myself. An incursion is an incursion, isn't it?
I believe the point was that airspace infringements happen - but usually result in a diplomatic protest, not the engagement and destruction of the aircraft and the death of the crew.
However, most don't occur when both sides have withdrawn their ambassadors, there is firing across the border and one is publicly admitting to hosting and supporting a rebel army conducting incursions into the other.
As for the region, I can remember discussing such matters with an Iranian colonel back in 1976 during a CENTO TACEVAL in Turkey shortly after the USAF lost a C130, rumoured to have been lured across a border using meaconing. Do you have any problems when aircraft cross the USSR/Iranian border?
"No", he replied, "If they cross we shoot them down, and if we cross they shoot us down. We both know where we stand".
