the benefit of American Military base

[love4peace]

Dear friends ,
i wanna know the benefit of American Military base in some another country .
let me give an introduction about this question ;
" the united states been known as the world's police , i was educated this in my school , during that time i was searching about this amazing country but i found allies for it .. lemme confess , no better police than the US , others just makes you think twice , whoever shall be the Police gouvernement is the USA because that your Justice Departement is so reasonable & i believe in it ."
try to prove me wrong .
more than that if something went wrong ,
it's sometimes the system & orders can fail the soldier this means we shall understand and handle the truth of some sad events ..in every war , that's not to be negotiated.
