[[WMG:Why did the government order a bombing run on Raccoon City?]]
The issue here isn't how the government knows about the outbreak; that's obvious. The issue is what they know that made them decide upon sterilization of the area, as opposed to sending in the CDC. This is a B-movie type game, yeah, but it could be an interesting plot point. Conspiracies abound...
* Resident Evil 5 clears this up. They ordered a bombing run because they'd gotten nervous with what Umbrella was pulling; the President felt he could blame the company for what happened and keep the heat off himself in the process.
** Another, more pragmatic reason. By the time of the nuke strike, nearly everyone in the city was probably already dead. Not a lot of reason to risk a lot of soldiers fighting zombies and B.O.W.'s in close combat for no reason when you could just incinerate the city.
*** Or it could be [[TakeAThirdOption all the above]].
** Confirmed with Resident Evil 6; part of the 'truth' the President intends to reveal about Raccoon City was the United States Government's connection to the Umbrella Corporation, and that the nuke was partially intended to cover this up. This results in his assassination/zombification due to concerns about the destabilising effect it may have for the US' political influence.

[[WMG:Nicholai is one of two things, "dead" not being one of them...]]
Seeing as no matter which ending you get in ''3'', the other games hint that he's still out there somewhere without covering up his possible deaths, I've decided that he's probably either:
* '''A:''' An EmpoweredBadassNormal. Probably a part-Tyrant like Wesker, which always opens up the possibility of him being a recurring villain after the whole Raccoon City scenario, or at least appearing in one future game. [[BrotherChuck Preferably one that includes Carlos.]] Though the fact that all serious villains seem to mutate/reveal themselves to be mutants would render that a little of a Wall Banger.
* '''B:''' A descendant of [[WhyWontYouDie Rasputin]]... Somehow.
** Well, he was Russia's greatest love machine.
*** In that case, Sergei could be as well - and so might H.U.N.K., it's not like we know his name or where he's from, and being MadeOfIron is his defining trait. Umbrella could have deliberately sought to recruit as many descendants of the TropeNamer for RasputinianDeath and could, at least so it looked, magically relieve hemophilia for U.B.C.S.

[[WMG:The Nemesis parasite is related to Las Plagas]]
Fairly simple: both are CombatTentacles-based parasites capable of making the infectee stronger and more resistant to harm. This also provides a more gradual transition between Resident Evil 3 and 4.
* Well damn you. I thought I was going to be adding a new WMG to the page, but no. I do have more evidence for it though. Yes, in addition to the tentacles and effects on the host, the NE-alpha was created by Umbrella's European branch, and Resident Evil 4's [=NotSpain=] is the only place known to have Las Plagas.
