Everything I read about Alaska and its process of statehood said that the main motivating fact was how important the state had proved to be in the Second World War, together with the experiences of hosting airbases etc. But in this timeline the USA has not even been in a war, except by proxy, and the wars that have been fought have been far from Alaska. Sure, Japanese annexation of Kamchatka might provide a wake-up call that begins to move things onwards towards statehood, but its not there already, whereas reading the history of Hawaii's bid it shows that attempts were made OTL in the 1930s originally, so I can see them pushing and pushing and getting there. As for the Philippines its history in this timeline is divergent; that needs to be remembered, these places don't suddenly come into prominence with OTL occurrences tagged on, but with twenty or so years of differing history from the timeline
