Why was Trump not told about the GRU/Taliban piece of intelligence?

The story is huge: the Russian GRU military intelligence service, filled with spooks, assassins, poisoners and basically the most aggressive intel service in the world today is supposed to have been offering bounties to the Taliban and/or its associates to kill American, British and other coalition troops in Afghanistan. The awful thing is it doesn't really surprise me. We know from the history of the GRU that they are capable of anything. Smearing totally deadly novichok on the front door handle of a former colleague who turned double agent to work for MI6 and got swapped in a Russian/UK deal and lived happily in Salisbury until the GRU came smearing. The Sergei Skripal case tells us everything about how the GRU carries out its business. The GRU is also heavily into cyber skulduggery. But paying money to the Taliban to kill American and British soldiers? That's a new venture. Surely if there was evidence about such bounties ie stashes of money found in raids on Taliban hideaways or signals intelligence linking the Russian agency with the Taliban or whatever, shouldn't Trmup have been told. If this was going on when the US was trying to fix a peace deal with the Taliban last year, the president and commander-in-chief should have been briefed. But Trump says he wasn't briefed. The director of national intelligence, John Ratcliffe, said the president wasn't told. Gina Haspel, CIA director, says he wasn't told and Robert O'Brien, national security adviser, says he wasn't told. Now Trump claims that he wasn't told because the intelligence community didn't think it was credible that the GRU was handing over cash to the Taliban. Really? I mean, really? They all knew about it. They all had discussions about what to do about it. But they didn't tell the president or the vice president because it wasn't worth passing on? I simply don't believe this explanation. It is true that the president of the United States isn't told everything about what is going on in the intelligence world. Presidents are not normally given all the operational details of some deeply secret intelligence mission. There is a need to know even for presidents. So in this case it wouldn't be necessary for the CIA, let's say, to tell the president all the ins and outs of a GRU plot in Afghanistan, but the basic stuff would and should have been included in the presidential intelligence brief that Trump gets every day. With American troops' lives at stake, the commander-in-chief needs to know. Something has gone wrong somewhere. But Trump's dismissal of the intelligence as not credible is the president's way of putting a lockdown on the whole issue. But there is a lot more mileage in this story. Nancy Pelosi wants a full briefing on why Trump wasn't briefed. I doubt the whole truth will come out but there are a helluva lot of questions that need answering.
