Would the world unite against aliens?

Considering the human tendency towards tribalism and conflict, uniting globally against an alien threat might indeed be a theoretical possibility, primarily due to a shared external threat. Jordan Harbinger discussed the concept that a common external threat, like an alien invasion, could potentially suppress human conflicts and unite humanity. This idea was notably echoed in a conversation between two world leaders, Reagan and Gorbachev, who agreed that they would set aside their differences in the event of an alien invasion 1.

However, it is important to note that any unification would require the threat to be credible and significantly alarming to overcome misinformation and deeply rooted national interests 1. The scenario is largely speculative and theoretical, relying on a high-stakes situation that forces global cooperation.
