Nuke Pusher
A country that leases nuclear warheads to other countries as this situation is very financially beneficial to the nuke pusher and it also enables the nuke pusher to exert influence on nuke junkies, essentially blackmailing them into doing things for the nuke pusher, such as by helping the nuke pusher to invade other countries; Nuke junkies will comply for fear of being charged a higher price for nuclear warheads or worse being denied a future lease of nuclear warheads with the nuke pusher.
The US Government is a Nuke Pusher.
