The British Empire (and to some extent, the Napoloeonic French Empire) is controlled by savants- technocrats who run Babbage's analytical engines. They are very smart, supported by most workers and the middle class, and have made nobility meritocratic. Babbage is described as a "master pragmatist" by a character, and the savants all have emergency committees that sit and plan out worst-case scenarios. Also, for some reason paleotology is sophisticated enough that people believe a comet wiped out the dinosaurs. It is conceivable that based on the book, some savant might have considered a future meteor strike.
Internationally-wise the British have beat up the U.S. by alternately supporting the C.S.A., California, Texas, and various Native Americans. The British have also opened up Japan to trade and advancement- they helped to kick out the shogunate and bring in a mikado.
Mexico is in Napoleon's hands. Sam Houston is a British-supported puppet- an anti-foreign junta took over Texas, and Houston fled to Britain with much of the treasury and attempts to amass a reconquista army in the beginning of the book. He gets assaulted by an assassin later, a Texian Ranger who demands for the money back, and mentions that the junta "can't feed ourselves", and lacks a lot of things.
Techwise there are steamcars, though not much mentioned about zepplins (thanks). About the same level as 2050 Peshawar Lancer world.
