Maybe it's 2 birds with one stone.Time for a little tin foil
What if the plane was shot down not because it was a mistake or deliberate but what if they shot it down due to something or someone being on the plane that they didnt want leaving.
1. Orchestrate a deliberate plane crash to demoralise Muslims and foment unnatural revolution in Iran, bringing the Iranian people into the Global System. Iran becomes Dubai.
2. Kill some of your dissidents at the same time.
I think killing dissidents is a secondary goal. There are no dissidents that currently pose a threat to the Global Elite. It's too easy to kill people these days and make it look like suicide. Look at Hillary Clinton's legacy of "suicided" dissidents. You don't need to resort to blowing up planes.
The most dangerous dissidents in Iran currently are the general population, who are asleep, and who don't realise the Iranian government are playing patsy and fighting a fake war with the West. These people must never be allowed to wake up.
I think the NWO gameplan has shifted from WW3. I would suggest that Iran's usefulness as a patsy has expired. Depopulation through War is an outmoded idea now.
The Global Elite has a new "bogeyman" that they will use to depopulate the Earth - Climate Change. They will use the climate to unite the world under their NWO system through droughts and floods, water shortages and food shortages. The Elites can actually control the weather now through weather modification technology, so they will be able to use this technology to scare the global masses into submission for years to come.
.....Or it might be War and Climate Change simultaneously, plus a Financial Crisis to top it all off. The NWO Elite have so many tools in their arsenal. They have even discussed faking an "Alien Invasion" to scare the masses into accepting the NWO;
