No it should not, but there were some statements made by holders of shockingly high Vatican positions which came very close to crossing that line.
I'm referring specifically to the statements suggesting that in the modern world war could never be justified without U. N. approval. The only way to square that with Just War theory is to assume the nation state is no longer a sovereign authority. Dangerous stuff, especially since it was sort of dumped out there without explanation or attempt to explain it in light of the soverign authority concept within Just War principal.
