Biden is a lame duck president with NO PUBLIC MANDATE and subterranean approval rating, he got ousted by his own party before the election for being mentally incapacitated, his defense against a Justice Department inquiry is he's too old and senile, his party just got BTFO in a national election. No NATO or NATO proxies have ever launched long range missiles into Russia in living memory. How is this guy 
fit for office
STOP EATING CRAYONS AND DO YOUR FUCKING JERB. "Senile old man sends young people to WW3 out of spite"
Yes American personnel are the only ones who can operate this technology. It is Joe Biden pushing the button to launch a close range missile strike into Russia. Sorry you love imperialists so much you refuse to accurately describe them, but that’s a you problem.
NATO personnel are also operating Patriot SAMs and other NATO equipment throughout Ukraine. If you doubt this you are beyond naive
