The 1991 Gulf War saw only 100 hours of ground fighting as U.S. forces entered Kuwait to end the Iraqi occupation, but echoes of that conflict have lingered for more than two decades in the Middle East.
The war pushed America into opening military bases in the Persian Gulf and Saudi Arabia, drawing the anger of an upstart militant named Osama bin Laden and laying the groundwork for al-Qaida attacks leading to Sept. 11, 2001.
Saddam Hussein, demonized as being worse than Adolf Hitler by President George H.W. Bush, would outlast his American rival in power until Bush's son launched the 2003 American-led invasion that toppled the Iraqi dictator.
Now, 25 years after the first U.S. Marines swept across the border into Kuwait, American forces are battling the extremist Islamic State, born out of al-Qaida, in the splintered territories of Iraq and Syria.
The Arab allies who joined the 1991 coalition are fighting their own conflicts at home and abroad, as Iran vies for greater regional power following a nuclear deal with world powers.
Iraq is now fragmented and war-torn to a degree few could have imagined after that 1991 U.S. victory.
The Islamic State jihadis have imposed their rule over many of the Sunni-dominated areas of the country, Kurds in the north have their own virtual mini-state and Shiites — many of them allied to Iran — lead the government in Baghdad.
In all, the United States finds itself in the quandary it hoped to avoid back in 1991.
"Had we taken all of Iraq we would have been like the dinosaur in the tar pit — we would still be there, and we, not the United Nations, would be bearing the costs for that occupation," the late Gen. Norman Schwarzkopf, commander of Desert Storm, wrote in his memoirs.
Iraq invaded Kuwait on Aug. 2, 1990, angry that the tiny neighbor and the United Arab Emirates had ignored OPEC quotas, which Saddam claimed cost his nation $14 billion.
Saddam also accused Kuwait of stealing $2.4 billion by pumping crude from a disputed oil field and demanded that Kuwait write off an estimated $15 billion of debt that Iraq had accumulated during its 1980s war with Iran.
Fearing Saudi Arabia could be invaded next, U.S. officials moved quickly to deploy troops to the region. After months of negotiations and warnings, the United States launched its assault on Iraqi forces in Kuwait on Feb. 24, 1991.
In purely military and political terms, the first Gulf War marked a tremendous success for the United States, which was still haunted by Vietnam.
America suffered 148 combat deaths during the conflict and 467 military personnel were wounded out of more than 500,000 deployed, according to the Defense Department.
The United States held together an allied army, its war effort was supported by a number of U.N. resolutions, and the conflict cemented its position as the sole world power following the end of the Cold War and the collapse of the Soviet Union.
America's Arab allies also footed much of the bill for the $61 billion war, with Saudi Arabia and Kuwait contributing some $16 billion, while the United Arab Emirates offered $4 billion, according to U.S. congressional reports.
Japan and Germany together contributed another $16 billion, while South Korea gave $251 million. The United States covered the rest.
The key players in the Arab world at the time of the conflict are now long gone.
Saudi King Fahd died in 2005. A popular uprising toppled Egyptian autocrat Hosni Mubarak in 2011.
Syrian totalitarian ruler Hafez Assad, a longtime U.S. foe who joined the Gulf War effort to reap billions in aid and diplomatic benefits, died in 2000. His son, President Bashar Assad, still clings to power amid a five-year civil war that has killed more than 250,000 people and flooded Europe with tens of thousands fleeing from violence across the region.
In Israel, the memory of Iraqi Scud missiles prompted the military to speed up a missile-defense program that included the development of its Iron Dome rocket-defense system with the help of the Americans. Then Prime Minister Yitzhak Shamir, a hard-liner, held back from retaliating at the request of Bush, who feared losing Arab support for the war.
Though American aid to Israel exceeds $3 billion a year, relations have been strained over stalled Palestinian peace talks.
Despite seeing his forces routed from Kuwait, Saddam clung to power and survived an uprising by Shiites and Kurds following the war. The United States and its allies began to patrol a northern and southern no-fly zone to protect the Shiites and the Kurds while Saddam remained a thorn in the side of American politics for more than a decade.
"I miscalculated," George H.W. Bush said in a December 1995 interview. "I thought he'd be gone."
It would take President George W. Bush's 2003 invasion to end Saddam's reign, coming amid the U.S. campaign in Afghanistan. In its aftermath, al-Qaida in Iraq would arise and be put down by a U.S. military surge, coupled with the support of Sunni tribesmen.
But as the United States withdrew from Iraq and Baghdad stopped supporting the Sunni tribesmen, the Islamic State emerged from the ashes of al-Qaida in Iraq and in 2014 took control of about a third of both Iraq and neighboring Syria.
Today, the United States is mired in a long war feared by Schwarzkopf and others who oversaw Operation Desert Storm.
