Better question to ask are who benefits and what was the regional track record. Who benefits at this time is pretty clear Ukraine and Israel. Ukraine into attempting to bring in international support. Things are not all hunky dory into Ukraine defence forces, they can not even properly feed their troops let alone pay them, the oligarch are too busy strip mining the country of anything they can loot and selling off the remainder to the US, so desperation is rising. Israel, another land based invasion of that Warsaw like ghetto Gaza, which will be kept off the front pages (there are highly skilled mercenaries from all over the world operating in the Ukraine, only temporarily loyal to the highest bidder). All prior rebel shoots down of aircraft were at low altitude, none at high altitude. Apparently a very high skill set of many operators is required to operate the system, definitely not point and click, strictly specialist trained operators.
The biggest indication of false flag, western media are trying to claim Russia shot down the aircraft without any reason why given and only mention the Ukraine government, the biggest benefactor in passing as a maybe might be.
