He believed that the Great Depression would not become as severe as it did and implemented many dubious laws that actually made things even worse like introducing a new tariff system which was supposed to help but actually destroyed foreign trade for example. He was easily beaten by Roosevelt who promised the new deal.
This question is really simple. The United States gained Guantanamo Bay, which is infamous today, for its prison.
The Guantanamo Bay Corrections Facility holds the most VIP terrorist inmates, and it's managed by the Central Intelligence Agency (CIA).
