I assume they're vulnerable to kryptonite? Would their weakness be known when they arrived? If that were the case I think defense systems would be set up for some areas, and their ability to rule would not be total.
Either way, some would welcome them and cooperate. They would form alliances and handle key situations. Even if they were known to be vulnerable to kryptonite, they could still make formidable adversaries. How much kryptonite would be available? If it were in limited supply they would just have those loyal to them deal with it. If plentiful supplies were available it could cause more problems for them, but short of peppering the entire globe with lethal doses of it, they would still control substantial portions of the world.
I'd say 40 wouldn't be able to directly control the world (unless we're bringing in things like time travel), but they would be able to rule by developing a loyal following to assist them.

One Kryptonian could do that. No need for 40.
