Has it occurred to anyone why they chose to make the kill in such an odd way and at such a public place place? Out of so many options they decided to use VX? At an airport? And they had to mobilize a trillion people to kill one middle aged man? I know the North Koreans are stupid, but are they that stupid???
VX is easy to get or make. You can mix primal unfiltered version of VX gas in a High School Laboratory, in the 1990s. The Japanese Cult Aum Shinrikyo (奧姆
真理教) have famously mix 200g of unadulterater VX Nerve Agent and try to assassinate 3 men, wounded 2 and Killed 1. It's quite easy once you know the forumula
This is the easiest of the Chemcial weapon you can get and if you mix it right, it's also the deadiest, you can mix it with counter chemical you buy in Supermarket and can be mixed with only basic Laboratory environment, that mean you don't need to bring anything over custom if you are trying to kill someone overseas, lowering your risk. Granted if you are mixing it in a High School lab, you are not going to get a near pure VX gas and kill a million people with it, but if you want to kill just one, it's more than capable of doing that.
All the direction point at N.Korea, so that is high possibility that they are involved. News mentions about those people are assassins group. Even by looking at the video, their action doesn't look like a prank. But would N.Korea hire assassins to murder Kim Jong nam? or those people are part of the N.Korea agents? Since those people sure don't look alike Korean and kind of amature where they were caught redhanded. One thing worth mentioning that is Intelligence of China failed miserable this time.
Using a third country agent is standard spycraft. Especially you want it to be a clandestine operation.
If you look at the opeartion as a whole. The execution (the action/assault that killed Kim Jong-nam) is quite flawless, the girls, enter the airport, execute the action, exfil the airport, they don't stammer, they don't wait, they dont hestitate, they know from the begining what they are doing, how they are doing it, and most importantly how to exit the airport without causing many fuzz or attention to themselves.
However, the second part of the operation, the exfil part is a diaster, one was caught leaving the country from the same airport, the other was caught in an Apartment building.
Now these suggested two things, 1.) They have drill, training on how to execute the plan of killing Kim Jong-nam, regradless whether or not they are working with North Korean or not, they have planned it, know where the target is and will be, know how to get out of the airport so you don't bump into things, know how to carry out the assault without many people notice.
2.) They have not planned the exfil. Rather, exfil was not prepared. You NEVER go back to the scene of the crime, let alone exiting the country using the same airport. You either leave IMMEDIATELY (board the next flight after you killed Kim out of the country) or you wait in a safehouse. Both weren't done properly.
Now, the closest sscenario I can think of with this happens is this
WHoever behind this attack train these two girls to carry out the plan, and promised them a way to leave the country, the plan carried out, but the one behind the attack is expecting both of them to be killed or death, thus, exfil was not planned. Now, either the party behind this assassination betray the 2 girls, and they panic and starting to make mistake, or the cell leader did not think of the exfil plan throught because they weren't supposed to be alive. This is the onlly way what happen make sense.
Or if anyone have any idea, I am all ears.
