So let's take your comments one by one
- Russian involvement in Syrian/ISIS conflict
Sure. This speaks to motive. There is no dispute that ISIS had the motive to do it. But motive is not evidence that something was done, only that one desired to do it.
- ISIS takes responsibility for plane
ISIS (and terrorists in general) take responsibility for things they don't do. They have a vested interest in looking more powerful than they are. So any such claim by them is self-serving.
- UK and US suspect bomb based on intelligence
Yes. But intelligence that has not be revealed to anyone. So it's not something we know.
- Action taken to change aircraft travel through airport
This is a mere inference. We don't know what the Egyptians know that caused them to do this. It isn't evidence that a bomb took down a plane.
- ISIS Paris attacks
What does that have anything to do with anything?
- Reports that CVR sound signature = bomb
Such reports are false. That has been explained in the prior thread already.
- Complete almost instantaneous in-flight failure of commercial aircraft is extremely rare
Truth. But so are terrorist bombings. So what is you point?
- Russian government states it was a bomb (I would not judge its current actions based on MH170)
Yes. But again like the USA and UK we don't have any data, just claims.
