A nation has every right to declare war for any reason it wants to. Morality does not equal legality. All that a war needs to be "legal" is for an official declaration to be made. The reason(s) for the war may not be morally suitable, but the legality is certainly there. "Legal" does not mean "right", any more than "illegal" means "wrong" (or vice versa).

There are international laws (every nation has to follow these) and treaties (that the US signed, i.e. the UN charter) that make any declaration of war without sanction of the UN or without an case of emergency illegal.
Illegal equals against the law. If you think doing something against the law is not unmoral, fine, but that's not the way most people see it. Next time a thieve robs you, he will say that it is illegal but hey, you have no right to think of him as bad or his deeds unmoral! It's just against the law, nothing more! So smile.
