Brother this is WW1, 25 years before what we’re talking about. And it wasn’t even an agreement, it was Germany sending a desperate proposal to mexico, strategically appealing to a nation that shares a border with its enemy’s. I wouldn’t call that an alliance and i wouldn’t call it relevant to WW2
Yes but WWI was the direct cause of WWII. WWI saw the dismantling of kings, a global pandemic, caused the depression, and left Germany with the bill for the entire war. This eventually led to the rise of the Nazis because people were starving and needed someone to blame (not excusing it, just giving context). In a lot of ways we are still living through the consequences of what happened 80-100 years ago. They typically gloss over WWI in school because it’s still relevant today (the Middle East)
