World War II: Thailand declares war on the United States and United Kingdom.

In 1942, Thailand declared war on the United States and the United Kingdom, aligning with Japan during World War II.
On January 25, 1942, the Thai government under Prime Minister Plaek Phibunsongkhram declared war on the United States and the United Kingdom. This decision came shortly after Japan’s rapid expansion in Southeast Asia and its invasion of Thailand. Thailand sought to preserve its sovereignty through alliance with Japan’s Greater East Asia Co-Prosperity Sphere. The declarations allowed Japanese troops to use Thai territory for military operations against Allied forces. The move sparked internal resistance and recognition of the Free Thai Movement. After the war, Thailand repudiated the declarations and was treated as a victim of aggression by the victorious Allies. This episode remains a complex chapter in Thailand’s modern political history.

The Battle of the Bulge raged from December 16, 1944, to January 25, 1945, in the dense Ardennes Forest of Belgium and Luxembourg.
