The BBC website reports:
"The half-brother of North Korean leader Kim Jong-un has been killed in Malaysia, South Korean and Malaysian sources say.---
Kim Jong-nam, 45, is said to have been targeted at the airport in Kuala Lumpur, the capital. A source close to the Malaysian PM's office told the BBC that Mr Kim was killed in the city, saying his body was now undergoing an autopsy. Kim Jong-nam is the eldest son of former North Korean leader Kim Jong-il."
The US President Mr Trump says 'something will be done' about North Korea's somewhat provocative ballistic missile tests. Perhaps one imagines a pre-emptive strike on military facilities?
Easily done, but it's hard not to see the Chinese reacting badly.
Something a little more subtle is needed. Some virus, engineered to attach to cells expressing a certain genotype. Thanks to CRISPR, that kind of virus-editing seems quite practicable. A weaponised flu variant should do it.
How to get a copy of the Dear Leader's genome? You can go a long way with a half brother.
The other half of the mission is transportation. The US authorities should not be relying on a pandemic. A long range stealth-drone delivering a miniature RPV close to the OL should do it: something disposable and wasp-like.
Send a swarm: only way to be sure.
What are the chances the CIA has this mission design in front of the President as we speak?
Greg Cochran was writing about jihadis, but the principle seems to apply.
