Honestly I sort of feel like the US would have been better off with a separate dedicated internal intelligence agency and a separate domestic law enforcement/investigation agency. The FBI is forced to kind of do both but doesn't necessarily do either as well as a dedicated agency.
I agree actually, as did apparently Truman and Congress post-WWII as that's what the CIA was SUPPOSED to be. Literally the "Central" Intelligence agency to which all US intelligence operations reported and which would collate and correlate all that information and propose counter-moves and contingency plans. Instead, with a solid core of ex-OSS 'operatives' used to and eager to continue doing 'hands-on-work' and more familiar with 'hands-on' operations we got a covert action group, (ANOTHER covert action group mind you) that immediately set out to compartmentalize it's operations and information which disinclined any other intelligence group to 'share' data or operations with them.
The CIA was supposed to FIX the problems with US intelligence found prior to and during WWII but instead... The CIA was supposed to operate both in foreign and domestic capacities but Hoover made it clear that domestic was his turf and he would not be cooperating or consulting with the CIA. Further since the founders of the CIA were in fact more interested in foreign operations and had the ear of both Truman and Eisenhower they had no real problem with this.
The thing is that you'd need a close working relationship and cooperation between a domestic intelligence and law enforcement agency so it made a lot of sense at the time to combine them since it was already clear the States were not going to be very supportive of such an organization. (The "United" States were still very much NOT that united even as late as the mid-30s
) The first Red Scare helped on the Federal level but didn't do much at the State level where it took the significant (and very public) issues with the 20s and 30s 'gangster' problem to finally get the States to relax the restrictions on Federal activities.
(I have to forgive some of the authors here who's time-lines tend to have Hoover and/or the FBI/Federal forces going from state to state and suppressing violence and lawlessness in the 20s and 30s since even American's have a hard time with history and especially that period. The use and allowances for Federal authority versus State authority were heavily in favor of the States and actual use of Federal forces needed a LOT of State government support and agreement. Hence for example why the FBI had to coordinate with local law enforcement because they couldn't arrest anyone, ask for a search warrant or even carry a gun!)
I just think pretty much anybody other then Hoover should have been in charge of said intel agency.
I agree, but... I'm no the fence a bit since at the same time I'n not sure anyone but Hoover could have managed the political and publicity factors to move the FBI forward in either capacity. He had the political savvy and could make the right connections and also had the media savvy enough to promote to the public is such a manner as he could undermine opposition from more local and State authorities.. But by the 1930s his 'influence' is becoming more of hindrance even thought the Bureau was finally coming into it's own. I don't know of any historic figure at the time who probably could have husbanded both (or either) a Federal law enforcement and intelligence agency through the birthing pains of the period.
