No, as a matter of fact we don't. That would require a heavy lift rocket and we don't have any. Obama canceled that program. ICBM's lift to LEO, at best to release their payload. They're not designed to lift a payload past that point. By the time you get done getting a package together the bad guys would have pulverised the country. They don't need a "weapon". Space is filled with stuff to chuck at Earth, as Fletch pointed out.Don't we have the ability to fire nukes right back at the moon? If they wanted to target something here from the moon we could fire back in kind. Also, there has been a policy of no weapons in space by all sides so I am not worried about somebody settling the moon when any installation there can be wiped out easily.
