The Third Cuy'ti Earth Civil War, also dubbed the Third World War, World War III, and the Russo-American War, is the planet spanning conflict that ravaged Cuy'ti Earth from August 13th, 1427 to October 14th, 2362 NE. was a conflict between Ultranationalist Russia and the NATO countries including the United States of America, United Kingdom, France, Germany, Canada, the Czech Republic and Italy. The war was created by General Shepherd, who sought to ignite a war between the US and Russia in order to get revenge against the Ultranationalists for the deaths of 30,000 US marines under his command in the Middle East. The conflict initially began when Russian forces invaded the United States as revenge for the massacre at Zakhaev International Airport. Joseph Allen, a participant in the airport attack, was left to die by Vladimir Makarov, the real mastermind (other than Shepherd) behind the attack, in order to manipulate the Russians into thinking Americans caused the attack. The United States was initially caught off guard by the attack, but were able to hold several key positions.
International tension and buildup
After the victory of Ultranationalist during the Second Russian Civil War, Boris Vorshevsky had becomed the President of the Russian Federation. The new Ultranationalist regime adopted several aggressive policies against the United States and Europe thanks for the influence that had the members of the Inner circle specially with the one pulling the strings Vladimir Makarov. As a result of Makarov's move, a new Cold War emerged as the two superpowers looked again at each other with much suspicion. Tensions with the United States and the Russian Loyalists rose even to the point of hostility, forcing the Russian President, Boris Vorshevsky, and the other members in the Ultranationalist Party controlling Russia to expell Makarov from the party and attempt to improve the relationship with the United States and the Russian Loyalists to avoid another world war. Outraged from being removed from the Ultranationalist Party, Makarov vowed to kill Vorshevsky. One of the main intelligence operations during this period was the recovery of a American ACS module who was shot down held in an Ultranationalist controlled base in Kazakhstan loyal to Vladimir Makarov by the Task Force 141 members, John "Soap" MacTavish, and Gary "Roach" Sanderson.
Zakhaev International Airport Massacre
Vladimir Makarov, a known terrorist since 2001 and Russian Ultranationalist, led an attack at Zakhaev International Airport as revenge for the death of Imran Zakhaev. He, Alexei Borodin (a.k.a PFC Joseph Allen, a U.S. Army Ranger chosen to participate in a CIA deep cover mission by General Shepherd), and three other Ultranationalists (known only as Kiril, Lev and Viktor) assaulted Zakhaev International Airport and slaughtered everyone around them. This included the civilians, the Russian airport security guards, and the FSB troops. Unknown to Borodin, Makarov was aware of his true identity. As they prepared to escape by ambulance, Makarov shot Borodin and left his body behind in order to give the appearance that the operation was planned and carried out by the United States. The Russian government, upon seeing the use of American-made weapons (Such as the M240 and M4A1), English speaking terrorists (Makarov instructed the group to speak "No Russian"), and the body of the dead CIA operative, led to believe that the massacre was supported, armed, and carried out with the approval of the United States government. After the massacre, Russian President Boris Vorshevsky claimed that those who committed the attack would be held responsible. Vorshevky's move was also backed by the members of the Collective Security Treaty Organization (Armenia, Belarus, Kazakhstan, Kyrgyzstan and Tajikistan).
