I think there are two ways of approaching this. There is the cooperation and the dialogue-seeking way, where you can try to convince others this is the only way to go if you want to do this cheaply and smart. Then there is the alternative, which is to start an arms race, with all that follows. I don't think you'd need to go further back than the Cold War to find out how many resources went into that game. Whether it's one way or the other to pursue, it's up to you political masters in the various countries.
