During world war ii, which battle was the first significant us victory in the pacific?
battle of the coral sea
battle of midway
battle of guadalcanal
battle of iwo jima

Though Battle of the Coral sea started first, It was in a Coalition effort with Australia's forces. I want to say the Battle of Midway, since it was a major blow in the Imperial Japanese navy, against the US Naval force. 

To have a bunch of countries to team up, and communicate not let the communist break them apart and take over the world

Treated as a slave is cruel and harsh
