lol, no, as I said, If I train some people and liable to its action then so should the world.
The person who is changing allegiance is not changing it because he or she got what they trained with by the US, he or she change their allegiance because of the attitude of the world, eg how he or she see the world changing.
If I train someone, not even need to someone overseas. Say in a police academy, what happen if that person gone thru the police academy but decided he or she could better use his/her knowledge to make money by committing crime? Then did the police academy would be accountable to his/her action? So basically, there should never be a police academy because the trainee may choose to become a criminal instead and by your logic, having an academy could use to support criminal. Because the police academy cannot have control over individual will?
This is not the same as the nuclear missile, you don't deal with nuclear missile in a day to day basis, and if you ask me, no country in this world should have nuclear missile to begin with.
The principle is the same. And why are you training foreign fighters for clandestine operation on a daily basis?
By your example if you are training someone through the police academy and he turn to life of crime, then you are responsible in arresting him and put him in jail. That's the responsibility of a government.
Well, or any store would not sell anything that can be remotely used as weapon.
Let me go to a local home depot and get a hammer.
Sale Clerk : "You sure you won't use it to kill someone"?
I said : No I won't
Then I turn around and killed the sale clerk with said hammer....And blame him for selling me the hammer...
Lol. Are you trying to draw a scenario in justifying Kim's action if he was to sell nuclear warheads to any non-state party?
