In the future, synthetic viruses will be unleashed which spread quickly, producing no symptoms — until they reach a targeted person whose DNA sequence unlocks the virus’s lethal abilities. The Atlantic reveals that preparations are already underway for this coming era of biological assassination:
The U.S. government is surreptitiously collecting the DNA of world leaders, and is reportedly protecting that of Barack Obama. Decoded, these genetic blueprints could provide compromising information. In the not-too-distant future, they may provide something more as well—the basis for the creation of personalized bioweapons that could take down a president and leave no trace.
DNA of world leaders is already a subject of intrigue. In the President’s Secret Service, Navy stewards gather bedsheets, drinking glasses, and other objects the president has touched—they are later sanitized or destroyed—in an effort to keep would‑be malefactors from obtaining his genetic material. Personalized bioweapons are a subtler and less catastrophic threat than accidental plagues or WMDs.
