18 years later, America vows to 'never forget' 9/11

NEW YORK (FOX 5 NY) - It’s been 18 years since the 9/11 attacks stole the lives of nearly 3,000 people; 18 years since the worst act of terrorism our nation has ever seen and the pain is still raw.

"Eighteen years. We will not forget. We cannot forget," Bud Salter, who lost his sister, Catherine, said at ground zero.

President Donald Trump laid a wreath at the Pentagon, telling victims' relatives: "This is your anniversary of personal and permanent loss."

"It's the day that has replayed in your memory a thousand times over. The last kiss. The last phone call. The last time hearing those precious words, 'I love you,'" the president said.

Later, former President George W. Bush, who was in office on 9/11, and then-Defense Secretary Donald Rumsfeld attended another wreath-laying at the Pentagon.

Near Shanksville, Pennsylvania, the third site where planes crashed on Sept. 11, 2001, Vice President Mike Pence credited the crew and passengers who fought back against the hijackers with protecting him and others in the U.S. Capitol that day.

"I will always believe that I and many others in our nation's capital were able to go home that day and hug our families because of the courage and selflessness of your families," said Pence, who was an Indiana congressman at the time. Officials concluded the attackers had been aiming the plane toward Washington.

Nearly 3,000 people were killed when terrorist-piloted planes slammed into the World Trade Center, the Pentagon and the field in Pennsylvania.

After reading part of the long list of names, Parboti Parbhu choked up as she spoke from the ground zero podium about her slain sister, Hardai. Even after nearly two decades, "there's no easy way to say goodbye," she said.

By now, the heritage of grief has been handed down to a new generation, including children and young adults who knew their lost relatives barely or not at all.

Jacob Campbell was 10 months old when his mother, Jill Maurer-Campbell, died on 9/11.

"It's interesting growing up in a generation that doesn't really remember it. I feel a connection that no one I go to school with can really understand," Campbell, a University of Michigan sophomore, said as he attended the ceremony.

Like the families, the nation is still grappling with the aftermath of Sept. 11. The effects are visible from airport security checkpoints to Afghanistan, where the post-9/11 U.S. invasion has become America's longest war. The aim was to dislodge Afghanistan's then-ruling Taliban for harboring al-Qaida leader and Sept. 11 mastermind Osama bin Laden.

Earlier this week, Trump called off a secret meeting at Camp David with Taliban and Afghan government leaders and declared the peace talks "dead." As the Sept. 11 anniversary began in Afghanistan, a rocket exploded at the U.S. Embassy just after midnight, with no injuries reported.

Al-Qaida's current leader used the anniversary to call for more attacks on the U.S. and other targets.

Nicholas Haros Jr., who lost his mother, Frances, reminded the audience of the al-Qaida attackers and tore into Democratic Rep. Ilhan Omar of Minnesota over her recent "Some people did something" reference to 9/11.

"Our constitutional freedoms were attacked, and our nation's founding on Judeo-Christian values was attacked. That's what 'some people' did. Got that now?" he said to applause.

Omar, one of the first Muslim women elected to Congress, has said she didn't intend to minimize what happened on Sept. 11, and accused critics of taking her words out of context. She tweeted Wednesday that "September 11th was an attack on all of us."

The dead included Muslims, as Zaheda Rahman underscored after reading names at ground zero. She called her uncle, Abul Chowdhury, a "proud Muslim-American man who lived his life with a carefree nature, a zeal for adventure and a tenacity which I emulate every single day."

Others made a point of spotlighting the suffering of firefighters, police and others who died or fell ill after being exposed to the smoke and dust at ground zero.

A compensation fund for people with potentially Sept. 11-related health problems has paid out more than $5.5 billion so far. More than 51,000 people have applied. Over the summer, Congress made sure the fund won't run dry . The sick also gained new recognition this year at the World Trade Center site, where a memorial glade was dedicated this spring.
