yeah but that's like drawing the same sized no deploy zone circles on every base and calling it a day. In some scenarios it works, in most it doesn't. With that solution, it might stop the spam but now the faction that strikes first is rewarded. It encourages using them earlier in the fight. Also encourages coordinated uses of them, so they can drop multiple nukes at once, before the timer triggers. Then the other faction can't retaliate. Honestly just removing them is the better solution over getting a headache trying to solve how to implement something that brings no depth to the game.
