The article you are referring to actually says the story is probably true, but that the confidence of the intelligence community in this finding is only "weak to moderate".
The much bigger problem was that Trump said outright this story is fake, instead of holding Putin's feet to the fire or getting behind the issue at all.
If every US president held Russia’s feet to the fire when the CIA had “weak to moderate” intel we’d be banging two rocks together for fire because WW3 would’ve happened already.
Because while trump was increasingly trying to isolate Russia for its bad behavior comrade Biden rolled over in his first meeting and removed a bunch of restrictions.
The story wasn’t that “Russia had a bounty on US soldiers” instead it was “Trump knew that Putin put out a bounty on US soldiers” neither story is true but you only really care about the second one because OMB.
The point is your crocodile tears are a sad excuse for caring.
