Pearl Harbor continues to reverberate. The attack on the United States Navy base by Japan on Dec. 7, 1941, shocked an insular nation into direct declared combat in World War II. Soon thereafter, in early 1942, a Gallup poll registered that overwhelmingly isolationist public opinion had been transformed into equally decisive support for engagement “in world affairs.”

President Franklin D. Roosevelt of the U.S. and Prime Minister Winston Churchill of Great Britain made a dramatic commitment to the concept of a United Nations. In fact, this profound move began before the Pearl Harbor attack, when the two leaders met off the coast of Newfoundland in August 1941.

Planning continued after Churchill made another perilous trip across the Atlantic in early 1942. Despite war demands, the Allies planned the post-war UN in remarkable detail.

Our blinders and mistakes before the terrorist attacks of Sept. 11, 2001, were more subtle in nature. We were guilty of short-changing national security needs, focusing on domestic agendas, and viewing terrorism as troublesome but still distant.

Beware of politicians who argue the world fundamentally “changed” in the wake of al-Qaeda’s mass murders in the Twin Towers, the Pentagon and the Pennsylvania field. That is a dead giveaway of ahistorical, self-absorbed leadership.

Our world remains, as always, uncertain and at times extremely dangerous. What ended as a result of the 9/11 terrorism was the American fantasy that the end of the Cold War had somehow rendered us invulnerable, contrary to history.

In our opinion: 19 years later, U.S. should renew its resolve against terrorism

Initial American response to the 9/11 attack demonstrated commendable maturity. There was no mass Muslim incarceration along the lines of the internment of West Coast Japanese-Americans after Dec. 7.

Pearl Harbor commanders Adm. Husband Kimmel and Gen. Walter Short were publicly condemned and cashiered. President George W. Bush did not seek political scapegoats for the Sept. 11 shocks.

Failure to foresee Pearl Harbor reflected interservice rivalry and bureaucratic turf-protection, plus arrogant assumptions that Japanese could not defeat Western forces. Arrogance came from historical ignorance: Japan’s Imperial Navy with astonishing efficiency had utterly destroyed the Russian fleet only a few decades before Dec. 7. Likewise, Sept. 11 was facilitated by secretiveness and rivalries among our intelligence and security services, and no little cultural arrogance.

Our world remains, as always, uncertain and at times extremely dangerous.

Pearl Harbor demonstrated Tokyo’s innovative use of tactical air power for strategic destruction of capital ships. American commanders were occupied with less imaginative threats. Even Adm. William F. “Bull” Halsey, more worried than most about a Japanese attack, and one of history’s great combat commanders in the Pacific War, was concerned primarily about submarine rather than air attack at Pearl.

Two outstanding books about Pearl Harbor were published many years ago. “At Dawn We Slept” by Gordon Prange and “Pearl Harbor — Warning and Decision” by Roberta Wohlstetter underscore the continuous challenge of securing accurate intelligence.

After the shock of Pearl Harbor, FDR, Gen. George Marshall and other U.S. war leaders, working closely with our allies, showed great discipline in realistic assessment of the enemy and extremely thorough long-term, as well as short-term, planning. U.S. voters should assess contemporary leaders — and aspirants — by this standard.

On a very practical level, the next U.S. administration should give high priority to permanent membership for Germany and Japan among the other major powers on the United Nations Security Council.

Their enormous economic success, effective representative democracy and support of the international community all argue forcefully for taking this overdue step.
