As an American (USAian), I tend to look at whether a TL is a Mexiwank/Mexiscrew by the location of the US/Mexican border. By my definition, If Mexico contains Galveston, Texas and San Francisco, it *is* a Mexiwank, If it contains Corpus Christi and Los Angeles, it is somewhat of a Mexiwank. OTOH, if Mexico loses at least 3 of the 6 current Mexican states that OTL border the USA, it somewhat of a Mexiscrew and if they lose any state which doesn't border the USA (other than Baja California Sur) it *is* a Mexiscrew. Of course there are those who say that OTL is a Mexiscrew (and an Ameriwank)... So how much do other changes in border or other TL changes affect the wank/screw ratio? Is a TL with loss of Sonora and Chihuahua & Baja to the US but with all of Central America down to the OTL Costa Rica a Mexiwank or a Mexiscrew?
