The Europe First strategy remained in effect throughout the war, however the terms "holding action" and "limited offensive" in the Pacific were subject to interpretation and modification by U.S. senior military commanders, and at allied leaders conferences. The strategic situation in the Pacific and related logistical requirements dominated the United States' actions after its entry into the war and led to an initial focus on the Pacific. Even in the later stages of the war, there was intense competition for resources as operations in both regions were scaled up.
