Is it very much in the interests of those presently running the US and EU? Absolutely.
Does this mean it was necessarily done by sinister evil western groups? Nope.
One should never assume malevolence when incompetence can adequately explain what happened.
IOW, let's use Occam's Razor.
Which requires the more complicated assumptions?
A. Evil western intelligence agency smuggles the rather significant equipment into a war zone, almost certainly after stealing it from the Russian government, then blows this plane out of the sky. Followed by extensive false-flag radio and cell phone traffic to make it look like the Russkies did it.
B. Incompetent, drunk and/or lost in the fog of war "separatist" militias and/or Russian agencies fires the missile and "accidentally" shoots down the plane, probably under the impression it was a military target.
To my mind B is a lot more likely to happen. YMMV.
One thing to consider when one starts seeing secret conspiracy everywhere is whether there is any possible evidence that would change one's mind.
If not, one is probably getting over the edge into believing by faith that everything bad is caused by whatever evil group you hold responsible for the world's problems. The problem is that sometimes things just happen, there is no secret conspiracy behind it.
Are there globalists willing to lie, kill, steal, start wars, or do anything else to promote their agenda? Certainly. Does that mean every single incident that takes place can be explained by a globalist conspiracy? If you do, you have become a lunatic.
After the last Malaysian Airlines plane that completely disappeared - and authorities for weeks spewed all about their “radar tracking”, which was a circus - I don’t trust anything about authorities saying there was a missile involved or there was not a missile involved.
IMHO, this just as easily could have been a bomb on board.
