Tournament of War: Anyone?

Long ago, I saw a cartoon or graphic which displayed a tournament bracket.  It was not of sports teams but of countries who have engaged in war.  The semi-finals of US v. Vietnam and USSR v. Afghanistan produced the finale of Vietnam vs. Afghanistan.  I cannot find it on the net, but here is my rough effort to remember it.

Anyone have the original gif/jpg file or something like it?  Want to make suggestions about how to revise it?
