Largely the U.S.’s responsibility to fight Japan
\
following Pearl Harbor Japan had lots of land occupation
\
MILITARY STRATEGY: The US Navy "leapfrogged" the Japanese-held islands in the Pacific. The strategy of island-hopping called for bypassing some of the most heavily fortified Japanese posts, capturing nearby islands, setting up airfields on them, and then neutralizing the enemy bases through heavy bombing. Deprived of essential supplies from the homeland, Japan's outposts would slowly wither away.

KEY VICTORIES:
\
Battle of the Coral Sea: Site of a crucial naval battle in which American and Australian forces were victorious over the Japanese. For the first time, the fighting was all done by carrier based aircrafts. Neither fleet saw or fired directly at each other.
\
Battle of Midway: turning point, where Japanese expansion was halted
\
Battle of Guadalcanal: In August 1942, American forces gained a toehold on Guadalcanal Island in an effort to protect the lifeline from America to Australia in the SW Pacific. A naval defeat at the hands of the Japanese shortened US supplies, but US troops managed to hold on to the islands for weeks. After a series of sea battles, in Feb 1943, Japanese forces evacuated Gudalcanal. Japanese losses numbered 20,000, while the US losses were about 1700 (this ratio would continue throughout the war).
