No need - Group Security keep a close eye on global developments...
The issue here is about
acting in developing situations and the prioritisation of commercial vs safety interests, where they conflict.
Since the Ukraine civil war started, an Il-76 has been shot down, so has an An-22 and a helicopter - the latest of several fast jets to be shot down happened on the morning of the 777 disaster. The airspace closure of Simferopol and even the official closure of Simferopol airfield itself was done extremely slowly, despite there being a Russian invasion. To say there have been indicators that this place is dangerous would be a statement of the obvious.
One thing is sure - ALL other carriers who have been treating East Ukraine airspace as a normal day out have dodged a bullet and will be breathing a massive sigh of relief (in private). Malaysian have not been so fortunate, but it could have happened to any carrier who chose to continue using that airspace.
I expect there will be lawsuits from passengers dependents. The press could properly spin this story and not just against Malaysian, they could question the industry as a whole. Some risks are accepted as part of aviation, but knowingly flying through a war zone to save fuel or access a destination is entirely at the discretion of the airline..
