I could limit my response to four words of results that refute this evidence-free innuendo: HIMARS killing ammo depots.
But I'll elaborate further since you cherry-picked Weisgerber's quote of Jed Royal, deputy director of the Defense Security Cooperation Agency, the arm of the Pentagon that oversees U.S. arms sales. Here's the part you dishonestly omitted:
"Royal said his organization is working closely with Ukrainian officials.
'“Communication with the Ukrainians has been extremely robust and the assurances that we have received from the Ukrainians about how they are handling these systems and protecting them, I will say, has been very robust and satisfactory,” he said.'
Supporting your argument with odd bedfellow and better-Russian-than-a-Democrat Trumpster Rand Paul gives away the game. You're at the naive useful idiot left end of a political horseshoe whose other half is inhabited by AFPACers and CPACers chanting Putin! and Orban!. You and they are direct descendants of Lindbergh, Father Coughlin and the Communist Parties whose slogan before June 22, 1941 was "don't fight the imperialist war". How poetically history rhymes with the delusional far left and far right singing from the same hymnal.
The Ukrainians obviously have a clear incentive--surviving a genocidal war--to throw everything they get from Nato at their Russian occupiers.
You then hint, with no evidence, that the black market for arms is doing well from western support for Ukraine. This is Russophilic disinformation like the idiocy about bioweapons labs in Kharkhiv.
Ukraine is not Iraq, Vietnam or Afghanistan despite your evidence-free attempt to paint it with the same color. You're squirming because an "alliance without limits" coalition of autocratic kleptocrats--Xi the Taiwan Squeeze-player and Vlad the Aimless Bomber--formed to finally make the Uncle Sam hegemon's military-industrial complex look good by comparison. When you argue with reality by trying to cherrypick your sources to bend reality to fit ideology instead of vice versa, you'll lose the argument every time. Evidence bites as hard as a pitbull and the sanctions that put washing machine chips in Russian weapons systems....and never lets go.
