You are missing the elephant in the room. A declaration of war is mostly illegal under most circumstances of international law. There are only a few circumstances under which such declarations may be legally possible, since the adoption of certain early 20th Century international treaties. Warfare is still lawful and even obligatory under these later international laws, but the warfare is not lawful by authority of a declaration of war in these circumstances.
Paultard apologists like yourself is the problem. If Paul gets it, we will not only lose, but even more dangerous would be the remote possibility he could become President. (A highly FATAL error on our part.)You are right in that fact as well.
Every treaty allows a nation the right to self-defense, even the UN charter.
