Earlier quoted context omitted.
They just want the US to keep their word on promises already made. Is that so unreasonable? They gave up their nukes for it.
The nukes were never under Ukraine control or possession. It's like saying Turkey has nukes, they don't, they are US nukes.
What is said by Russian propagandists is that Ukraine didn't have the launch codes - like it was some magical barrier that would prevent Ukraine from deploying the nukes if they wanted to.
Like Ukrainian scientists didn't play a major a role in USSR nuclear development, and didn't have the know how to just use other system to deploy the nukes.
It's part of the Russian propaganda to make Ukrainians into incompetent inferior ethnic group - why do you think they address them by derogatory ethnic slurs like "little Russians"?
