One image shows smoke billowing from the World Trade Center. Another depicts the iconic hooded prisoner of Abu Ghraib. Nearby, Osama bin Laden and a grim promise that the “worst is yet to come”. Finally, a simple message: “USA: Fear Eats the Soul.”

This is not propaganda spread by radical Islamists hell-bent on crushing the United States. It is part of a new exhibition at the Whitney Museum of American Art in New York that devotes a whole section to the post-9/11 epoch.

The Whitney styles itself as the “pre-eminent institution” for US art. Its selection of post-9/11 works is bleaker and more unsettling than other shows on the theme, and projects a disturbed nation that still struggles with the events of the past 14 years.

“We looked at a lot of work made since 9/11 and noticed many artists presenting a troubled United States, if you will, post-9/11, post-Hurricane Katrina, post-recession, and what we began to think of as a changed world order,” Jane Panetta, one of the curators, told Al Jazeera.

“The works reflect a problematic period for the country. That the US was in a moment of national struggle and international struggle. On a global stage, both in terms of our actions and of outsiders’ perceptions of the United States.”

The works appear as the Course of Empire section of the Whitney’s retrospective of US art, called America Is Hard to See, which runs until September 27 and celebrates the 85-year-old gallery’s new premises in the city’s chic Meatpacking District.

Americans are used to seeing 9/11 depicted as a national calamity, with artworks about jets careering into towers that act as solemn tributes to the nearly 3,000 people who died in the strikes and the first responders who tried to save them.

Scrap metal from toppled skyscrapers has been used in a sculpture that lionises firefighters. Underprivileged New York youngsters have stitched together The 9/11 Peace Story Quilt, which asks: “What will you do for Peace?”

The so-called World Trade Center Cross, intersecting steel beams that were found amid the rubble, remains on the tourists’ check list at Ground Zero. On Friday night to mark the anniversary, the twin blue beams of the Tribute in Light will once again brighten the skies above Lower Manhattan.Meanwhile, the National September 11 Memorial & Museum is presenting a photo series by Jonathan Hyman of murals and graffiti memorials that sprang up across the US. They feature American flags and such mottoes as “united we stand” and “this means war”.

In one instance, a two-storey home in Connecticut was decorated as a massive Star-Spangled Banner. Similarly, Hyman’s show features a beefy New York firefighter who devoted his entire back to a tattoo honouring colleagues who “gave all”.

Back in 2011, several New York art shows marked the 10th anniversary of the attacks; they focused on the event itself and its aftermath. In a contemporary review, the New York Times said the shows “rekindle grief” by reviving an “intense and confusing panoply of emotions”.

“I’ve seen a lot of bad work that came out of 9/11,” Stephen Stapleton, co-founder of Edge of Arabia, an art project that began in the wake of the attacks to build bridges between the West and the Middle East, told Al Jazeera

“A lot of bloody towers made out of different materials and artists who approached the subject too literally.”

The show at the Whitney marks a departure from schmaltzy patriotism.

Two pictures by Aleksandra Mir set the scene. Her cartoonlike versions of newspaper covers from 1998 are eerily prescient, with bin Laden, head of al-Qaeda’s network, warning “the war has just started” and the “worst is yet to come”.

Keith Mayerson’s 9-11 is a whimsical and dreamy oil painting set at 9:03am on that eventful day, seconds before the second hijacked airliner slammed into the South Tower. It is less grandiose than other versions of the tragedy.

Abu Ghraib, by sculptor Richard Serra, is a lithograph of a hooded captive in the eponymous Iraqi prison, where US forces tortured inmates after the 2003 invasion as part of former president George W Bush’s so-called “war on terror”.

Other pieces show the US in decline and disorder. Rirkrit Tiravanija’s contribution declares: “USA: Fear Eats the Soul”. Artist Wayne Gonzales presents Dick Cheney, the hawkish vice president of the period, with an upturned US flag above the phrase: “So Long Suckers”.

Glenn Ligon’s neon sign, Rückenfigur, shows the word “America” with inverted letters; curators suggest the nation’s “sense of gleaming promise is shadowed by doubt”. Ed Ruscha’s painting The Old Tool & Die Building shows America’s decay via a graffiti-covered factory that has been bought by Asians.

“The show raises questions about our expectations, as audiences, on whether we anticipate art to be more patriotic when it relates to 9/11,” Livia Alexander, an expert on Middle Eastern and American art, told Al Jazeera.

“Artists often take on a more critical approach and show more troubled aspects of society. Good art pushes us, pokes holes in our thought and makes us think, feel, reflect and respond.”

The events of 9/11 have doubtless left a lasting mark on the American psyche; the Whitney’s show follows years of soul-searching about the attacks and their legacy in Afghanistan, Iraq, Syria, and the Guantanamo Bay detention centre. Al Jazeera
