Okay, I'm not technically asking for Burma as a Great Power, though that would be kind of cool to see. What I want is actually something more along the lines of Burma managing to resist colonization by the British and industrializing - I imagine that this would rather naturally lead to Burma managing to attain a status similar to that of OTL Japan, which was considered a Great Power at least for a time.
Basically, what I'm asking for is a logical/realistic series of events that have Burma remain uncolonized/independent, industrialize without getting taken over and become at least a regional power.
