Outrageous! The Kaiser himself prefers to let innocent citizens of the Reich suffer and perish rather than to "offend" the Pope? By his own words he states that the defense of Jerusalem is more important than our own homelands! This is a clear example of how the Reich is rotting from the inside.
Any man who gives preference to the security of Outremer over the lands of Franconia, Swabia, Austria, and Bavaria is not worthy of calling himself a Roman. Any man who cares more for a foreign alliance than the welfare of his own people is not worthy of calling himself a Roman.
This is not a matter of risking excommunication from the Church. No Bavarian wishes to bring such harm to our people. This is a simple choice between causing the Pope some small displeasure or allowing misery and suffering for the commoners of Bavaria! The Kaiser so arrogantly says that the Milanese can "wait." Wait? Which Elector here would simply "wait" when his lands were being repeatedly devastated by invading armies, his vassals raped and killed, his merchant ships taken, and his ports blockaded? Any nobleman who would stand aside and "wait" to avoid the displeasure of an ally is not worthy of noble blood.
Kaiser, I fear that in the search for Chivalry you have forgotten what that word means. Chivalry means sacrifice of oneself for the betterment of one's people. Chivalry means doing what is right, even if it is difficult. Chivalry means upholding justice, no matter the cost!
