I don’t know which troglodytes you were dealing with - Arabs?
But F-16s have been in service the world over for decades, used by what it seems to be unlikely characters, like the Pakistanis. Who don’t have a US contractor presence BTW.
Ukrainians are the same racial stock as the Russians, who seem to deal with advanced aerospace maintenance well enough. A lot of the Soviet aerospace industry was in Ukraine pre-1991. Ukraine was a “high tech” part of the Soviet Union.
It’s always funny to read the stuff from the Pro-Zelensky-Ukraine-Happy About The Corruption & Money Laundering, Installed by Nuland & the State Dept Ukrainian Government that violated two treaties and Committed Attrocities against Russians Living In Ukraine.
Everything you and your ilk say is pure speculation based on what you want to happen with zero proof.
You have zero knowledge of the average Ukrainian citizen or member of their armed forces. A force which has been decimated, that is now co scripting teenagers and men in their 60s.
As for the Pakistanis, sadly, they are considered an ally. And they don’t get the fancy version of anything. They get the export versions.
