Governance,fed judiciary/ US Marshals, defense/military,, trade. All others are fluff and need to be disolved. We do not need any bases on foreign soil unless we are their to do some pay back. We do not need troops on foreign soil.let japan, europe union, and korea tough it out on their own. Withdraw from our mil ind complex wars with a severe bombing campaign of nations infrastructure on the way out. We should not, with our weaponry be entangled in any conflict for more than 5 years. If that entails a few hundred thousand dieing, then there won't be any eagerness to start throwing stones by the offending people any time soon there after. All alphabet agencies with the exception of the US Marshals is unConstitutional.Kick the UN out, they are a corrupt institution. All IMO of course
