I'm rereading the Tripartite Alliance Earth timeline again, and noticed that they had this happen-

Despite the harsh winter of 1916-17, the North Sea and Atlantic Ocean saw a series of decisive naval battles. In an attempt to choke off the transatlantic supply lines of the Western Allies, German U-boat submarines were dispatched to torpedo merchant vessels regardless of their nationality. Although Britain ran short on matériel for a time, the U-boat attacks on South American-flagged merchant vessels finally provoked the countries of South America -- first Brazil and Chile, then Argentina, Uruguay, and Venezuela -- into declaring war against Germany in January and February of 1917.

Granted, one of the points of that timeline has Latin America both stable and prosperous enough to be of the first world (while the U.S. falls apart in the '80s), but in OTL could South America have become involved with WWI, somehow?
