I find it interesting, in general, in this thread, that so many people dismiss what on the surface is a contrarian view (i.e., drastically reduce our overseas military presence), without more open debate.
Maybe my idea is wrong, but I feel it is worth a conversation.
for what? a smaller deficit? it's unclear whether reducing the size of the defense industry helps the US economy, so maybe you get a smaller deficit but you also raise unemployment by a couple % and lower economic growth by a % or so over the next 25 years
conversely, it's pretty clear this does hurt its current hegemonic position. that's a gamble not many are willing to take so carelessly
I say this as a non-American, by the way
