There's a rough equivalent to the Cold War freezing up (if that's the right expression) between the British Empire and China right now, mainly over questions of geopolitical influence in Africa and the Middle East, as well as the Indian-Chinese border.As usual, I’d like to know more about the Cold War and the conflicts that the US fights in. Both within the nation and outside.
As for the US, they've been pretty quiet on the international conflict front: the Spanish-American War happened as OTL but the US did not participate in either the Wilhelmite Wars (1914-17) and the Nine Years War (1937-46) and there is a strong movement in the Republican and Progressive Parties for military cuts as part of a government efficiency drive. The US military is generally thought to have underperformed during the Philippine Uprising, though, so that might focus/change minds.
