President Barack Obama was wrapping up a solemn address announcing the death of Osama bin Laden in a Special Forces operation in 2011 when he made a call to the nation’s better angels: The United States would overcome terrorists, he said, by holding true to its ideals as “one nation, under God, indivisible, with liberty and justice for all.”

On Sunday, President Trump chose a different note in capping his own announcement of the death of Islamic State leader Abu Bakr al-Baghdadi in a similar raid.

Baghdadi “died like a dog,” Trump declared, employing one of his favorite insults with his customary bravado. “He died like a coward.”

The deaths of the al-Qaeda mastermind in Pakistan and the Islamic State chief in northwestern Syria each represented an important strategic and psychological victory for the United States in the fight against terrorism and extremism, proof that the world’s most powerful nation was willing and able, through the dedication and bravery of the intelligence community and military, to hunt down and eliminate the enemy — even if it took years.

For both Obama and Trump, the moments represented a measure of vindication — evidence that each had demonstrated the resolve as commander in chief to finish the job in the face of considerable risk and criticism from the opposing political party.

But if Obama’s nine-minute speech in the White House’s Cross Hall was notable for his measured tones and appeals to the enduring strength of America’s values, Trump’s 50-minute performance in the Diplomatic Reception Room was marked by the overt showmanship, blunt language and airing of personal gripes that have defined an approach he once dubbed “modern-day presidential.”
