Not sure anyone heard of National Command Authority. The decision to launch nuclear missiles is not in this Generals wheel house. This comment he made is just silly. It is like him saying he supports the right to arm bears.. If he fails to follow orders he would be removed/fired on the spot if not by the SecDef then by Trump. As much as I hate Trump. This statement is just silly he made. To do a pre-emptive nuclear strike has nothing to do with LOAC. We can easily do a pre emptive nuclear strike..This Generals comment is about as pointless as many of Trump's tweets. It is a distraction.. If you noticed the General was not fired for making such a statement as what he said means nothing.
