Funny, just incorrect.
I did crack a smile for this cartoon short.
The problem with the message/theme is that it generalizes a very sensitive issue for events that affected millions of people in different ways. Also, linking the winner in the toon to America isn't very apt, considering we just pulled out of Iraq this month and Saddam Hussein is no more. The only territory we leave behind is an embassy and a tiny consulting force for their security training.
Unless you meant Afghanistan... which is a giant international peace keeping initiative now. We'll leave soon enough.
The majority of wars (and their death tolls) incited in the last 1000 years owe their beginnings to revolutions or desires for territory and resources on the part of a country's leader (Napoleon, Hitler, Mussolini, Hirohito, Pol Pot, Stalin/Trotsky/Kruschev, Andrew Jackson and his poisonous Manifest Destiny here in America, King Henry, the warring territories of Italy, the Mongol Horde (Directly responsible for the Black Death) I could go on and on...
If anything though, Americans can be proud that we have given back land over the past 100 years to their rightful owners on many occasions: Panama, the Phillipines, Japan (and by extension liberated China), Germany, now Iraq, and soon Afghanistan. It's true America seemed to make war too quickly in the most recent cases but it is bucking history by defying the trend of tyrants to hold onto territory and strip resources dry of their peoples.
I'm done lecturing. Hope you read up on some of these examples though; very engaging stuff.
