Why is "Thailand in World War II" trending?

Wikipedia Overview

Thailand officially adopted a neutral position during World War II until the five hour-long Japanese invasion of Thailand on 8 December 1941, which led to an armistice and military alliance treaty between Thailand and the Empire of Japan in mid-December 1941. At the start of the Pacific War, the Japanese Empire pressured the Thai government to allow the passage of Japanese troops to invade British-held Malaya and Burma. After the invasion, the Thai government under Plaek Phibunsongkhram considered it profitable to co-operate with the Japanese war efforts, since Thailand saw Japan as a partner who promised to help it gain some of the Indochinese territories. Following added pressure from the start of the Allied bombings of Bangkok due to the alliance with Japan, Thailand declared war on the United Kingdom and the United States and annexed territories in neighbouring countries, expanding to the north, south, and east, gaining a border with China near Kengtung.
