Oh Davys identifies himself as a Ukrainian pilot and that is enough for the Ukie trolls - now everything he says must be taken as received wisdom. Were you thinking propagandists identify their actual employer?
You have to be joking about the ‘accountability’ when Republicans in Congress are pressing for an accounting of funds spent. You really will push the MSM ‘narrative’ as if it’s fact, and anything said by Ukrainian trolls must be lawfully admired as fact as well.
As for accountability, there are about 100 US military personel in Ukraine. There is the military attache, embassy guards, and the Military Delivery Team making sure equipment goes where its supposed to. This is what Military inspectors are doing in Ukraine (link). Someone has to do the paperwork for what is going to Ukraine, and they have to do it according to the requirements set by Congress.
