Obama says isolationism offers a "false comfort." He says Pearl Harbor, the Sept. 11 attacks and recent terrorist attacks in the U.S. prove that "oceans alone cannot protect us."

Obama delivered the commencement address to U.S. Air Force Academy cadets in Colorado. By tradition, the president delivers the graduation speech at one of the four service academies each year.

Obama used his speech to urge the Senate to ratify treaties he says allow the U.S. to lead allies. He specifically mentioned the value of NATO — a rebuke to Republican presidential hopeful Donald Trump who has suggested the NATO alliance is outdated.
