Novel idea for a quiz but... not including countries that don't trade with the US I believe ruins it. I mean... $57,000 in imports? What was that? A 2nd hand Mercedes someone bought off of Tuvalu's Craigslist? Would make sense to put in all the ones that were at 0.
If I included territories, the US imported $6,000 worth from Pitcairn... Anyway, on imports only Cuba and North Korea are $0, and the USA exports to every single sovereign nation. The way I see it, if they are $0, they aren't trading partners.
