NCR (Pro) vs Caesar's Legion (Con)

Envision a hypothetical scenario, in which you are in a cave in the Middle East, by a stone, formerly blocking its entrance, now rolled away. As you enter with a team of archeologists, you find a dead man wrapped in a bloody cloth. Pierced in his sides, holes in his hands, whip marks from lashes abound, and a crown of thorns pressed onto his head. An inscription is present from Joseph of Arimethia, saying that he took the body after his crucifixion and concealed it there. You have found the body of Jesus Christ. Essentially, this would be the death of Christianity. Imagine the chaos after the discovery of the death of the Son of God, who never really was quite so. One just needs to replace the Jewish Nazarene with Caesar and the Cult of Mars, and you more or less have the same situation (sometimes he is worshiped as a god, other times as a divine prophet). But Caesar's situation is worse. Ignoring the fact that the foundation's of the theocracy have been pulled right from underneath itself, you have the exigent political problems. One might ask, why couldn't a Legate usurp leadership of the Legion as CosmoJarvis has proposed. But I must answer this question with another question, which Legate gets the title of Caesar? I'm assuming you mean Lanius, and depending on your choices, he may become Caesar. Lanius, the blood thirsty maniac who asks to murder the survivors of his own tribe after joining the Legion. Lanius, the man whose name in Latin literally means butcher. Lanius, the man who has the disapproval of Caesar and the leader of frumentarii, Vulpes Inculta. This is the man that you think will prosper the empire after Caesar's death. Besides that, what evidence does my opponent have that he can replace Caesar in his cult of personality? None. In the words of Caesar himself "Some might call him a great man, but I'm not sure he qualifies." Inevitably, Caesar will die, whether it be from assassination, war, sickness, or the brain tumor (Father died from cancer quickly in Fallout 4, and they actually had good medicine). Much like after the death of Muhammad or Joseph Smith, sectarianism will thrive no matter what. Onto the portion of allies and enemies. In one of the endings, Mr. House does too have a full house, taking over the hoover dam. But logically speaking if we are talking about a battle between the NCR and the Legion, Mr. House has everything to gain by joining the NCR, and everything to lose he joins the Legion. They aren't the biggest fans of technology, and especially securitrons. That very fact is a non-starter for a relationship between the two, because of his army of securitrons, and the very fact that the senescent Mr. House himself is, for all intents and purposes, one. Also due to the fact that the Legion derides intoxicating beverages and gambling, you aren't exactly going to be having a Caesar's Palace. The Legion and Mr. House mix about as well as honey and rancid goat milk. The Legion too has its enemies, such as the Raiders. The Omertas only choose to attack the Strip because of their lust for power. If the opportunity came, they have no ideological ties to the Legion and could very well betray them. And you have the some of the same problems as with Mr. House because of their casino. How about technology? A war in the Mojave would not easily allow for Guerilla warfare, due to its primarily desert terrain. Typically, in war, a faction wins either by using newer technology or using older technology better than everyone else. And the latter only really works in special circumstances, like the Vietnam War where the Viet-Cong was being helped by the Soviet Union and Communist China. I've proved that the NCR has much superior technology since they have vertibirds and power armor. My opponent's Camplorn Hope that he constantly cites as somehow being an example of the NCR being inferior to the Legion, making an exception the rule. But of course, this is one town of many. The President isn't going to send a dying town to battle, he's going to send the whole backbone of the army. Compare this to Caesar's army, where most of the army is the lowly Legionnaire, who is first set up with only crude machetes, improvised throwing spears, and antiquated firearms to battle their foes with. Only the most advanced warriors get advanced weapons such as thermic lances to anti-materiel rifles. In conclusion, the NCR would beat the Legion, due to their superior technology, their ally Mr. House, and the inevitable death of Caesar causing religious/political shambolic chaos throughout the Legion. For my opponent to win, he must at the very least explain how the Legion will survive the death of their "god", and Mr. House's allegiance to the NCR.
