Frankly, I'm happy that TFA doesn't get into the details of the politics of all of this like the prequels did.
Who did they use while they were waiting for their 'recruits' to grow up?
And who did all the recruiting? Was it Ex-Imperials?
Why aren't they in the upper ranks of The First Order?
Did they start off as a baby stealing outfit, then secretly start training the babies as soldiers?
Who funded them?
They have a lot of soldiers. Did no one try to get their children back?
Did no one else reject their conditioning?
Did they only take human babies that fit the uniforms?
These are all genuine questions,
I'm curious for answers as there was very little background on the First Order in the film.
How could you train a one week old baby?
