What if USA sent 10000 troops to invade japan mainland in 1945

If the USA had sent 10,000 troops to invade Japan's mainland in 1945, it would have likely resulted in a significant increase in casualties on both sides. The Japanese military was prepared to defend their homeland at all costs, and the fighting would have been fierce.

The invasion would have also required a massive logistical effort to transport troops, supplies, and equipment to Japan, which could have been difficult given the distance and logistics of the time.

Furthermore, the Soviet Union had already declared war on Japan and invaded Japanese-held territory in Manchuria. It is possible that the USA and the Soviet Union would have clashed in Japan, which could have resulted in a broader conflict.

Ultimately, the decision to drop atomic bombs on Hiroshima and Nagasaki, which happened before any invasion plan was carried out, is considered to have been a key factor in Japan's surrender
