Eurofed, sorry but i have to said this: You Americanphile start to Sick me(in general your concept of AH start to be a little cliched for me, someone must make a Wikin page for you and the eurofedism)
The POD of this TL is since the ARW, and the USA and extremly different than was suppose to be originally(taking away all the Deep South Culture, your change a big point in American Expansionism and Jingonist agenda since their birth but some butterflies can still want them have the warm pacific port and later the Fillbuster against Hawaii) and the British have their own expansionist agenda but their are more... refinated(in fact with their Dominon, they absolutily will advice them to NOT pushed away against another independant states besides those who the Motherland have a war or reason of hate) but if the mexican made the idiot mistake(they made it in OTL, the butterflies maybe are not too strong yet or the mexican are idiots by nature, sorry Dexter my mexican friend, but History them to support that thesis), in the Long Term... California will be a Integral of british souther america(with a partition/buy with the USA) or become a Dominon of their own...
The butterflies have a lot of power, is the abillities of choose was is the correct effect than separate a TL to be the history than never was or a big shit ASB

P.S. Where are thou, EF(I always think on you like a Irredentia Italian, maybe form the old Yugoslavia, Ilyria or Trento)?
P.S.2. EF, you should read Jared Magnum Opus in AH: Decades of Darkeness(or will be so strong for you, because that have an Hansburg dominated grossdeutchland with having Venetia being integral part of Deutchland, a Divided Italy(north and south), and Slave-holder USA superpower, and a Russia Super power)
