Excerpt:

Here is a list of outdated U.S. military bases overseas that can be promptly closed to save billions of dollars each year…

Close Outdated U.S. Military Bases in Japan – Futenma & Atsugi

Pull Aircraft and Airmen Out of Osan – now in a kill zone

Cut Army Fat in Korea – 8th Army and Daegu

Vacate Two Army Bases in Germany – as once planned

Close Torii Station – a U.S. Army base on Okinawa?

Vacate RAF Lakenheath – the Russians aren’t coming

Close Gitmo, the Entire Base – it has no purpose

Close Chinhae Tomorrow – it commands nothing

[There is more argumentation about each of these at the source.]
