Honestly, I do not know how members of the largest and most powerful intelligence agency in the world are appointed, but it is clear that it has an internal law regulating assignment operations that it is not in its interest to disclose, and there is no reason to disclose it outside official work circles.
Of course, one of the main reasons for not disclosing the composition of the members and the methods for their appointment is that none of them is liable to accountability, nor is the body itself. Almost all of us know about the responsibility of this apparatus in many tragedies around the world, and I do not remember that it was explicitly accused of defaming it, whether by the US administration or international organizations.
But the important thing is to know that the head of this administration is nominated by the President of the United States and approved by the US House of Representatives Congress.
Bush, Sr., before he was President, was CIA director for some time. It was during his presidency that the USSR collapsed.
Putin was KGB, the Russian counterpart of the US CIA. That's why the KGB took over operations right inside the Russian government, at the top level. It was their method for blocking the CIA.
Now, since the CIA is blocked by the former KGB from manipulating Russia from within, they are doing what they can to manipulate Russia from without... this time from Ukraine.
Since Bush's father was a Nazi supporter, Bush was right in on what Nazi's were all about, and their vicious tactics. Leftovers from those tactics are what the Bush-trained CIA is using right now.
Of course we will never know the details of the whys and whats of the things the CIA is doing to take down Russia, or the various methods the CIA is being repelled by the KGB-Russian form of government. But knowing these things shows us why the war is there as it is.
It's called Bush/Nazi/CIA/US-Government/Ukraine-Government against KGB-Russian Government.
