Whatever the truth of the nationality, politics etc. of the missile team that was responsible for shooting down this civilian plane, I believe it was an unintended shootdown, a mistake.
It's become all political and it's all down to assigning blame, scoring political points and even looking for some economic advantage, whatever that might be.
This

happens in war, it's happened before and it'll happen again.
Outrage is gonna sell a lot of newpapers and keep folks writing thinkpieces for weeks.
Colour me pessimistic.
