This is absolutely key. Much like in Alan Moore's graphic novel *The Watchmen*, humanity was forced to band together to fight off a greater, outside threat. Our greatest cities are in rubble, many of which were capitals, the imaginary lines which divided us are a relic of the past. The attack and attempted extermination of the human race was a huge wake-up call. We can't allow petty fights over trivial matters divide us anymore because there are very real problems to face, very real threats which are outside of our scope of vision. 

We go on by acting like a one-world civilization instead of independent states. It's not Independence Day in the United States, because there are no more United States. It's Independence Day for Earth.
