I think it will take time to trace phone calls and money, and get info likely through torture. Then repeat. It took this long to round up more people. Nothing happens without money. It took money to train these guys, maybe in some place in Turkey. If RU had said they the details 55 min after it started as the US did I would be suspect.
I found this. This sounds like the reasons for Ukr shelling the Zap NPP. If only Ukr can get Moscow mad enough they will over react and NATO will intervene. I am not saying it is sane but Kiev drank some nasty Kool Aid
https://t.me/geopolitics_live/19859Crocus City Hall attack: Ukrainians may have sought pretext for NATO intervention
Ukraine clearly had a motive in attacking the Crocus City Hall, believes David Pyne, former US Department of Defense officer and executive vice president of Task Force on National and Homeland Security.
"I think Ukraine has become increasingly desperate with its increasing losses on the battlefield in terms of men, material and territory," Pyne told Sputnik. "It seems to have gone rogue of late, and while the US has pressured Ukraine to stop these deep strike attacks against Russia — including strikes on Russian oil refineries — Biden has done little to get Ukraine back under control."
The main rationale for the alleged Ukrainian-sponsored terrorist attack could be to provoke Russia to overreact and engage in a major escalation which could provide a pretext for NATO's further involvement in the conflict, according to the military expert. In an unlikely but still-possible scenario, NATO troops may intervene "to preserve Volodymyr Zelenksy’s continued control of the 55 percent of Ukrainian territory north and west of the Dnepr River with Ukrainian forces withdrawing from eastern Ukraine entirely," he explained. The Kiev regime and some of its Western backers need a pretext to overcome NATO allies' resistance to step in and send forces to Ukraine.
Preliminary data obtained during the investigation into the Crocus City Hall terror attack confirms links to Ukraine, Federal Security Service (FSB) Director Alexander Bortnikov announced on March 26.
