SDI is amazing but for 75 million you'd have to either be a top 10 nation or be about to enter a nuclear war >_>
Also O_O at Federal aid commission. But let's face it, how often is the big nation the one getting paid in cash?
I can't see myself getting any of these except maybe the foreign air force base
