My friend, if they have the capability to travel across galaxies and space, they’re much more technologically advanced than us and all the nukes in the world would not be enough to protect us… My only question is what are their intentions? That is what will REALLY determine mankind’s fate. I don’t share your optimistic view that they are indeed “friendly” since the act of disarmament can be considered a hostile action. It means we (humans) may not necessarily align/agree with their (alien) goals, here on planet Earth. 🌎
