Look, it's simple.
The Twilight war, regardless of your timeline, background, etc requires manpower.
There is only a limited pool of manpower.
The military are drawing on every able body they can lay their hands on.
The CIA, FBI, NSA, and every other alphabet organisation want people to expand to meet the needs of wartime.
NOBODY is going to be allowed to retire, resign, quit, etc while there's a build up going on. Therefore, there's likely to be a huge shortage of manpower.

That's T2K for you anyway. If it's not a global war situation you're talking about, then's it's a different matter, but you're still going to face extreme difficulties from the existing agencies who feel their turf is being threatened.

The other question is, where the hell is the money coming from? Running an intelligence organisation doesn't come cheap and gold plated toilet seats only cover so many black ops...
Sure the start up cash might come from the example in your first post, but what about ongoing costs? Maintaining the organisation is nearly as expensive as setting it up in the first place.
