What are the 3 most important events concerning the us since 1990 and how has the country dealt with them?

The United States and its allies open a long-threatened war to drive Saddam Hussein's army from Kuwait, striking Baghdad and other targets in Iraq and Kuwait with waves of bombers and cruise missiles.

President Hashemi Rafsanjani of Iran offers to serve as a mediator between the United States and Iraq to seek an end to the Persian Gulf war. Iraq has no immediate public reaction, and the overture is received coolly by the administration of the first President George Bush.

A tank battle between allied armored units and Iraq's Republican Guard help bring the seven months of war in Kuwait to a close. Hours later, President Bush orders allied forces to suspend offensive military operations against Hussein's isolated and battered army. In an address from the Oval Office that is televised around the world, the president calls on Hussein to send his commanders to meet with allied officers in the war zone within 48 hours to settle the military terms of a permanent cease-fire.

Iran announces that it will sign a contract with Russia to complete a nuclear power plant on the Persian Gulf coast, but it denies a report that it may be less than five years away from producing nuclear weapons. The site is at Bushehr, Iran, which is thought to be the nation's most active center for nuclear weapons research and production.

early human migrations are the earliest migrations and expansions of archaic and modern humans across continents and are believed to have begun approximately 2 million years ago with the out of africa migration of homo erectus. this initial migration was followed by other archaic humans including h. heidelbergensis, which lived around 500,000 years ago and was the likely ancestor of both denisovans and neanderthals. early hominids were said to have "crossed land bridges that were eventually covered in water" .

within africa, homo sapiens dispersed around the time of its speciation, roughly 300,000 years ago.the "recent african origin" paradigm suggests that the anatomically modern humans outside of africa descend from a population of homo sapiens migrating from east africa roughly 70,000 years ago and spreading along the southern coast of asia and to oceania before 50,000 years ago. modern humans spread across europe about 40,000 years ago.

the migrating modern human populations are known to have interbred with local varieties of archaic humans, so that contemporary human populations are descended in small part (below 10% contribution) from regional varieties of archaic humans.

after the last glacial maximum, north eurasian populations migrated to the americas about 20,000 years ago. northern eurasia was peopled after 12,000 years ago, in the beginning holocene. arctic canada and greenland were reached by the paleo-eskimo expansion around 4,000 years ago. finally, polynesia was peopled after 2,000 years ago, by the austronesian expansion.
