This isn't true at all.
The 90s were a hideously violent decade. It was inevitable due to the power vacuum and weapons proliferation that resulted from the fall of the USSR, as well as several other brutal governments whose terror both held back and instigated future violence. But it ought not to be forgotten that behind the glitz of the web boom lay an awful lot of corpses.
Russia was engulfed by the Bratva, and crime topped even the horrors of the US in the 70s. The US itself was still under the thrall of the crack crisis, which we resolved with the same brutal policing and chilling prison sentences which now leave us with entirely new problems we're nowhere close to resolving. Worst of all, North Korea deliberately went through a famine that topped even the Great Leap Forward and Ethiopia in devestation all so the cockroaches who run the Hermit Kingdom could retain their absolute power.
Wars in Africa caused the sort of suffering the planet hadn't seen since the 40s: including the Algerian Civil War Osama and his buddies played a part in; the Liberian Civil War which had Syria-level casualties; the Rwandan War and Genocide, and the Congo Wars it helped exacerbate. The Second Congo War was so expansive in scope, it attracted involvement from countries all over the continent and left between two and five million dead. More than any war since the Fall of the Axis.
Islamofascism wasn't as poisonous as it is in modern times, I'll grant. But the 90s had a lot more ghild and a lot less gold than people like to remember.
