The Russians had thought about doing this during the cold war and the American states were strongly against it. Just because the Russians were going to use it as part of their war machine doesn't mean the States won't try.
The Russians liked the idea of lighting up a night battlefield or darkening one, as well as melting ice caps to create floods in valleys below and starting mass bush fires and increase UV rays, etc.
I don't approve the idea because its side stepping the underlining problem of CO2 emissions. Why not lower those instead of trying to put a giant foil wrap in space.
