It's a difficult question to answer because of the dynamic nature of conflict zones and international safety, but I will say a few things.
Post-MH17, the Dutch did a significant amount of work and made progress in relation to ensuring the safety of international civil aviation. As well, the ICAO has changed a number of its standards and recommended practices related to the manner in which conflict zones are managed and assessed by airlines and by countries. That was the big impetus to the safer skies initiative and why Canada seized the moment to build on the great work by the Dutch after their tragedy to build on international co-operation, to share information, to share intelligence, so that properly informed risk assessments are made so that, in fact, airlines are aware of and stay away from dangerous air zones.
