What other nation did Germany want to get involved in the war against the US?

Germany sought to involve Mexico in the war against the United States during World War I. This was primarily through the Zimmermann Telegram, in which Germany proposed a military alliance with Mexico, encouraging it to reclaim territories lost to the U.S., such as Texas, New Mexico, and Arizona. The interception and publication of this telegram in early 1917 fueled anti-German sentiments in the U.S. and contributed to America's decision to enter the war.
