Nukes can fly, but for that transit you get far more opportunity to shoot them down. Bigger issues are "why are they bothering to target Mars, there's not much there" and "oh wait, that was a great place to stick a second-strike capability, Outer Space Treaty LOL, so of course it's being targeted".
