None of us possess enough knowledge to accurately conclude what occurred in Moscow. It is speculation on all sides.

My argument with you was in regards to critical thinking/logic.
It doesn’t matter how many items point towards “A” being true, it doesn’t make “B” false. It requires just one correct negation.

You could have a bunch of circumstantial evidence pointing to Bob as being the murderer. Financial incentive, scorned lover, previous acts of violence…
But a video of him across town at the time of the murder negates everything circumstantial.

It’s quite possible that multiple theories about the Moscow attack are partially true. It could involve ISIS, and it could involve the CIA. Just run the truth tables.

Either way, innocents have been murdered and there will be payback.
How many Iraqis flew planes into buildings on 9/11?
How many Saudis?
Which country was destroyed?

In the real world, evidence is assessed and judgments made, with hypothetical possibilities built on mere imagination and supposition rejected for lack of evidence. I know how it is done, having been in more than a few courtrooms and assessed and argued legal and factual issues from death penalty cases to small claims.

As for the attack on Moscow, the evidence of ISIS involvement is already persuasive: ISIS claimed the attack as theirs and provided video that was shot on the scene by the attackers as proof. In addition, as reported by Russian authorities, the attackers used passports from Tajikistan and at least some were Tajiks. There is no valid basis for thinking that Ukraine was involved.

For generations, Tajikistan and other Muslim states to the south of Russia have been a security concern. As for pointing fingers at the CIA, US influence and credibility in that region collapsed after the US withdrawal from Afghanistan.
