During the end of 1958 till the beginning of 1959 Mexico and Guatemala had a small border conflict that could have lead to war. I even read once that the Mexican Air Force developed a plan to knock out the Guatemalan Air Force. This got me thinking, what if either Guatemala or Mexico did declare war and hostility broke out? How would that war play out? Would other Central American nations get involved and on whose side? What would be the response and role of the US and the OAS? What really interests me is the impact of such a conflict on Mexican politics...would this lead to stronger opposition against the PRI resulting in a PAN victory decades before PAN manage to defeat the PRI in elections? And what kind of butterflies would this release? And, would a POD before the OTL conflict be required to make any of the nations capable of sustaining a war effort? From what I know, Mexico would have some logistical issues with sending troops into Guatemala and a sustained war would be certain doom for any central American economy, as far as I know. I am thinking of doing a basic timeline with this, But there's still much for me to read, like tracking down a few sources, names, people, political and military dispositions...etc...Based on that I am not sure how detailed it would be (or accurate). Edit: I wrote down the wrong years. I was off by one year. I have made that change in my post now.
