I actually meant the opposite, that other NATO countries didn't do the same thing under similar circumstances, that Turkey's response was disproportionate to the level of threat. I don't believe Turkey only wanted to put a stop to Russian airspace violations, that's only a pretext. I think Turkey caused this incident to disrupt the cooperation between Russia and NATO in the area while portraying themselves as victims of Russian aggression. That's the only play that makes sense to me which actually could have made up for all the repercussions that followed and helped Turkey's interests if it have played out their way.
Erdogan is practically a dictator in a democratic country, he will do whatever it takes to stay in power, including siding with the enemy to keep the Kurds in check. His actions keep sabotaging the collective effort to stop ISIS, he is clearly not on board with Western agenda. If his "friend" is the biggest enemy of the Western world, that's more reason for me to believe that the motives behind this incident are far more sinister.
To me every life is important, that's why I chose a career in the medical field. And no offense but veteran pilots are not expendable, they are one of the country's most valuable assets and their death being facilitated by a friendly/neutral country is not irrelevant. There is no war between Russia and Turkey so lethal action is almost never warranted in these scenarios.
As a conclusion, was Turkey withing its rights to shoot the plane down, yes. Do I think Turkey had ulterior motives for shooting down the plane and it had nothing do to with standing up to the Russian bear, absolutely!
