[MIB][Independence Day] After the events of the first movie the MIB have to cover up the whole thing. What does this plan look like?

The entire agency got erased from existence by a powerful alien that wanted to watch earth burn. Other members of his race eventually notice this act. After they kill him they decide to undo his erasure but not the invasion of earth.

At that point they wouldn't cover it up. The whole point of cover up is preventing humanity from imploding on itself with the knowledge of alien life. Given the aliens tried to commit mass genocide against humans, then the status quo is dying in ignorance or dying with full knowledge.

If MiB wasnt completely destroyed, they'd likely be restructured into a global diplomatic agency. Then seek out as much help as they could against the invaders. There's a good chance alien nationals from other worlds were killed in the invasion. Their respective government would not take kindly to someone killing their own willy nilly.
