I think ISIS attack. The US and allies warned of an imminent attack and pretty much described it
Putin even publicly suggested it was nonsense and propaganda by the US.
What would the motivation be to then let that attack happen, I get it as a false flag and that has happened before it’s not beyond Putin at all but in these circumstances, I really don’t get that.
I also don’t get the slow response, if Putin wanted to allow the attack then you’d be better off stopping it at the start to prove how great you are at protecting the people rather than what actually happened. The slow response time really doesn’t look good for Putin
So for me ISIS attack, incompetent response but I have no idea if those are the real terrorists that were caught
It would be just too odd for the US to warn of an attack and then Russians deny it as propopganda and then carry out a false flag attack of their own that matched it. That would just be really strange
