Strange, the U.S. Military killed 18,000 Japanese non-occupiers.
"In July 1944, US forces retook the island of Guam after weeks of fierce fighting, leading to over 7,000 American casualties and over 18,000 Japanese killed."
Out of context. Guam was NOT occupied by the Japanese till they invaded it in 1941. Saipan was occupied by the Japanese prior to WWII.
