PLEASE NOTE: This timeline is under construction.
Nothing can unite humans like a common enemy. Time and time again, circumstances have forced previously hostile forces to come together for the sake of the common good.
That is, essentially, what this timeline is about.
"At the end of humanity, when all seems dark and forboding, we, as humanity, must join forces to save ourselves and our species. The outcome of this battle determines whether there is a humanity for the next thousand years. Humanity expects every man and woman to do their duty.
Good luck and godspeed."
- President Dwight D. Eisenhower, July 14, 1957
On July 11, 1957, humanity encountered an alien race known as the Sen'kaal. Humanity attempted to commence diplomatic realtions with the enigmatic extraterrestrials.
Unfortunately, the Sen'kaal did not reciprocate.
And so began the Human-Sen'kaal War. The technologically superior Sen'kaal made their initial landings at three points on the Earth's surface: Leavenworth, Kansas, USA; Omsk, Omsk Oblast, USSR, and Batangafo, Central African Republic. Under President Eisenhower's orders, nuclear missiles immediately were launched, obliterating Leavenworth. Khrushchev followed suit, annihiliating Omsk with over twenty nuclear warheads, and then Batangafo. But the aliens were not to be deterred. After a pause of about thirty minutes, the onslaught began in force, with masive Sen'kaal battlecruisers entering the atmosphere and deploying troops across the world. The UN declared a state of planetary emergency, suspended the Geneva Convention, and ordered every nation on Earth to begin mandatory conscription of all able-bodied perons nine and older. Depite these drastic measures, however, UN forces found themselves on the defensive. Over the course of the next four days, sixty percent of the world fell under Sen'kaal control. Even nuclear attacks on Sen'kaal troops seemed unable to stem the massive tide of the maelvolent aliens. But, then something happened that turned the tide in favor of humanity. On July 15, 1957, the Sun unleashed what is believed to be the largest solar flare in th Earth's history. The radiation-sensitive Sen'kaal troops aboard the battlecruisers and other vessels in orbit died an agonizing, quick death, as did the estimated 53,600,000 Sen'kaal ground troops deployed on the side of the Earth facing the sun at the time. Many of those on the dark side of the Earth suffered debilitating or even fatal radiation exposure. The survivors, devoid of any orbital support, were routed by human forces over the course of the next four days. From this day forward, July 15 was celebrated across the world as Miracle Day.
The Human-Sen'kaal War, or, simply the War, was effectively over.
All in all, the War had resulted in the deaths of around 900,000,000 humans worldwide. The Earth was pockmarked with craters, and large regions of the globe had been left uninhabitable due to the radiation caused by nuclear weapons. Rebuilding would take the next twenty years to complete. The Earth had accquired a massive, spectacular ring of debris and abandoned or destroyed Sen'kaal stations and vessels. In addition, the nations of the world had been left with an unintentional parting gift from their alien adversaries - the world had been left littered with alien technology.
After the dust had settled, the world was a very different place. The Soviet Union had collapsed into chaos, as its government's bureaucrats had severely neglected the common people, concerning themselves primarily with their own personal safety. Israel found itself at war with its neighbors again, who accused them of colluding with the Sen'kaal. Tibet also used the chaos as an opportunity to secede from the PRC.
The UN Response
The UN managed to stabilize most of the the conflicts that had sprung up in the wake of the War, granting the PRC permanent representation on the Security Council, as well as extensive monetary aid, in exchange for giving up Tibet. UN peacekeepers also stopped the war in Israel (which became known as the Fourteen-Hour War due to its brevity) and convinced Israel to give the Palestinians full independence.
However, the choas persisted in one place- the Soviet Union.
The Soviet Union, although instrumental in holding back the Sen'kaal onslaught, quicky began to disintegrate following the end of the Human-Sen'kaal War. Its government had sowed the seed of discontent during the war through its employment of nuclear-scorched-Earth tactic that, while highly effective, were carried out without the slightest regard to human life. After the de facto UN victory, Moscow's blunders continued with their gross mishandling of reconstruction and government aid to the people of the USSR. Their policy of prioritizing aid for Russia itself over aid for the Soviet Republics and Warsaw Pact was the last straw. Nikita Khrushchev was forced to make massive concessions to the Soviet Republic to prevent a mass mutiny of the Soviet Army, finally stabilizing the crumbling USSR.
The Scramble for X-Tech
The nations of the world soon realized the significance of the alien technology that had been left behind, properly termed "xenotechnology" but commonly called "x-tech." The U.S. was the first to begin collecting x-tech, founding the Special Research and Development Agency, or SRDA, on July 31, for the sole purpose of gathering and studying any x-tech that could be found. The SRDA quickly issued a national call for alien artifacts, and thousands responded with everything from alien assault rifles and communication devices to an entire landing craft (pulled out of the Willamette River in northwestern Oregon). The UK followed suit, forming the National Xenotechnology Collection Agency, or NXCA. The USSR, in turn, created the Military Research Board (Военный совет исследований, or VSI). Countries across the globe followed suit. In response to the so-called "X-Tech Rush," the UN passed a resolution declaring that x-tech found in a particular country is automatically that country's property.
A Unified Front?
It quickly became clear to the world's nations that the Sen'kaal would return someday, and humanity had two choices: be ready or face extinction or subjugation. Although the UN's drastic conscription measures were quickly repealed after the War, several resolutions were passed that increased its power in times of crisis. Meanwhile, nations realized the need to cooperate, which lessened the Cold War significantly. The nations of the world also began working to obtain more advanced military technology, leading to accelerated space programs and much more advanced technology than in OTL. The United Nations also began the construction of the largest structure ever built by mankind - the Citadel, a titanic continuity-of-species bunker built under the geological formation known as the Canadian Shield, a formation which contains some of the hardest rock on the planet.
Cold War Tensions
The War had, for better or for worse, forced the Americans and the Soviets to put aside their Cold War differences if only for the sake of solidarity. The Space Race became less of a race between the Americans and the Soviets and more of a race between humanity and time.
Eventually, this will become a live timeline.
