Unfair share? Based on what? The spending is directly correlated to USA's interests, there is no nanny-ing or "good will" going on, it's a matter of purely international interests. Looking at this with the patronising "unfair share" is a bit preposterous.

I'd say it's pretty unfair to a lot of countries being forced under the sphere of influence of the US to be continuously subjugated, through foreign policy or direct meddling in internal affairs, like the whole of Latin America. That is really fucking unfair.
