In December 1941, before the attacks on the US and the British Empire, Japan attacked which other country?

Thailand was never colonised, not by a single country forever. Honestly, Thailand was almost part of Empire of Japan and also it's like Switzerland but in Asia. Instead of avoiding all wars like Switzerland, Thailand was like keep changing sides so to avoid colonisation. They just simply did not continue the fight with the Japanese aggression as it would bring them colonisation.

the Japanese had no idea what was coming their way

I just randomly guessed and got it right 😂😂
