If they let loose the Swine flu (or Spanish Flu) of 1918 - or something akin to it - that'd be bad. That's the 5% planet-killer. The fun-one that killed NOT the infants and elderly. The trick with that particular strain of flu was that the healthier and stronger you were - the better your own body could self-destruct. Fast too. The method of death with this one is curiously familiar if you're a fan of early pandemics (they pumped a ton of fluids out of one patient recently). https://en.wikipedia.org/wiki/Spanish_flu#Patterns_of_fatality Excellent film on it (60 min) : http://www.pbs.org/wgbh/americanexperience/films/influenza/ Bitchute mirror : https://www.bitchute.com/video/ekZXCcB0lczN/ So let's run some numbers. 7.8 billion on Earth. 5% ... 390 million dead. China 1.4b x .05 = 70 million dead. US Population 330m x .05 = 16.5 million dead. It's already been detected in LA, Seattle, TX, and TN. Looks like rents are about to go down and job openings are going to go up if that sucker (or something very much like it) is on the loose.
