The information underlying this question, namely that the Iran-Iraq War was only 6 weeks long, is incorrect. It was eight years long and the longest conflict in the twentieth century. It was so long because each side dug in its heels and refused to compromise or surrender.
However, Operation Desert Storm, the liberation of Kuwait from Iraq in 1991 and part of the completely separate Persian Gulf War of 1990-1991 did only take 6 weeks. This was because the Coalition forces were substantially stronger than the Iraqi Army.

The Battle of Atlanta fought during the American Civil War lasted Six weeks.
Pretty much the only thing that was gained from the first battle of Bull Run, was that this war was not going to be over in a few weeks, like most of the country thought, but that the Civil War was going to be a long and bloody affair.
This is incorrect. The Iran-Iraq War was the longest war in the 20th century at 8 years and was only resolved by UNSC Resolution 598 since the money to fund the war was running low.
