World War II, for example, ran counter several of these criteria, yet both sides thought they were right, the Pope did not take sides, so the doctrine was theoretical only.
A couple of examples from World War II. The Armenians and the Finns, among various others, fought as allies of the Nazis.Ukrainians welcomed the inavding Nazis. Sounds bad, of course, but the Armenians wanted their legitimate freedom from the Soviet Union - and the Finns had been attacked by the Soviets in 1939. The Ukrainians wanted their freedom, too. Even in the Pacific, Thailand allied itself with Japan (and Gandhi was put in jail)?. Why? The French, British, Dutch and US controlled much of southeast Asia (India, Burma, Vietnam, Indonesia, Phillippines, etc.) and the Siamese and others wanted them out - Asia for the Asians (the Japanese slogan). Gandhi was jailed because he also wanted India free.
How did the Iraq War (II) rank? And in Afghanistan? And Vietnam? And Korea? We could go on and on. Even back to World War I and dozens of other major conflicts, many between Christian and even Catholic nations.
If the doctrine worked, it would be terrific. But obviously it hasn't.
