American-Coalition War

The American-Coalition War is an ongoing major conflict between the forces of the Confederation of South American States, the ACEP, the Orion Space Defense, Republic of Valmeria, the Neo-Valerian Confederation, Imperial Arkanian Empire, Republic of Serendipity, Austro-Japonic Union and Deniksol High Command against the forces of the United States of America and its ally, Neo-China.
The American-Coalition War is the second war fought against the United States of America by the coalition forces, the first of which was the Astral Talons-USSAS War. Most combatants from the AT-USSAS War returned to fight in the conflict.
== Background ==
=== The Americas ===
The United States and the CSAS already did not have good relations due to the AT-USSAS War and prior events. The OSD, located north of the mainland United States, also began to not have good relations with the USA. Also due to the last war, United States defenses such as the border wall and military bases were not at their full potential, as the wall was heavily damaged by the Arkanian bombardment. The United States Starfleet was also depleted because of the loss of 110 Freedom-class Space Battleships at the Javarian Front alone.
=== The Pacific ===
Tensions between Neo-China, Japan, and Russia also rose during this time, with fear of a Chinese invasion high. Neo-China recently separated from the USA but remained its ally. China was also expanding its Navy at this time.
== Rising Tensions and Pre-War Events ==
=== Pacific Tensions ===
Tensions rose in the Pacific between USSAS China and Japan and Russia. The CSAS sent a fleet of two destroyers and a carrier to help protect their allies. The fleet would be stationed in Vladivostok.
=== Dissolution of the USSAS and AT ===
The United Sovereign Sino-American States disbanded into the United States of America and Neo-China after the AT-USSAS War. They would still remain allies but were no longer in a union. The Astral Talons would disband into ACEP, India, and Korea which would later join the AJU. ACEP would continue to have poor relations with the ex-USSAS states.
=== CSAS Spy Aircraft ===
A civilian airliner mistakenly flew near a United States naval base located in the Gulf of Mexico but did not cross the US-Mexico border. CSAS drones soon escorted the aircraft away from the naval base. However, the drones were controlled from within the airliner, which contained no passengers. The drones performed reconnaissance and took photos of the US naval base along with the ships in port. The aircraft and drones were able to return to a CSAS base in Mexico successfully.
=== United States Troop Mobilization ===
Following the CSAS airliner incident, a force of 55,000 US Army soldiers was sent to the southern US border to form a defensive line against a CSAS invasion. The US Army would work with the US Border Patrol to look for breaches in security and light airfields were constructed for helicopters.
In response to the small CSAS fleet dispatched to Vladivostok, the USAF sent multiple anti-ship squadrons to Cuba. Unmanned experimental hypersonic aircraft were sent as scouts, cruising at very high altitudes making interception impossible. Images of ports and other strategic targets were captured, and US satellites were used to capture photos of other CSAS assets. The USAF also dispatched anti-submarine aircraft, while plans with China to increase naval defenses were created. Soon after the US mobilization, United States President Toad resigned as president, and Vice President John Lee took office.
=== Increased Militarization ===
As global tensions rose, multiple factions began militarization. The OSD began mass-producing VTOL attack 
drones and assault mechs. The ACEP mass-produced bots and began conscription, while supplies moved between the ACEP's territories. The Chinese government contracted the Ovis Security PMC to defend their coastline emplacements
The CSAS mobilized a large number of soldiers, numbering more than 700,000 strong, near the US-Mexico border. Tanks and other vehicles also began to be stationed at places near the border. Both Arkanian colonies, the Netherlands, and the Philippines mobilized their navies and military bases were placed on high alert.
=== United States and CSAS Withdrawal ===
The CSAS and US governments began cooperation to move their mobilized troops away from the US-Mexico 
border. The CSAS moved its 700,000 soldiers and their vehicles away from the border, while the US did the same. Small detachments of US forces would stay in the area to maintain a level of security equivalent to what was there before the US reinforcements arrived.
After the withdrawal of US and CSAS soldiers, a small Valmerian task force was dispatched from the moon and positioned itself near Earth to defend Valmerian bases in Venezuela.
== War ==
=== The First Attacks ===
Two Valmerian Midnight-class Battlecarriers warped into the Earth's atmosphere and sent interceptors to areas 
where the US violated airspace, such as the CSAS islands and Mexico. The Valmerian fighters came down on the US scouts and aircraft still in the area and successfully destroyed them. Then, the Valmerian craft changed course and attacked strategic targets in Cuba, such as military bases. 
After the first attack, Valmerian dropships dropped infantry and vehicles in Cuba near SLAM platforms. Due to near-complete air superiority, the infantry and armor were able to quickly take the SLAM platforms and established Valmerian military dominance in Cuba. Valmerian ground forces, at this point, had captured most US airfields and other military targets.
In space, smaller Valmerian starships entered Earth's orbit and tracked down US satellites, firing cruise missiles at them and quickly destroying them.
=== Other Factions Join ===
Shortly after the Valmerian attack, the Orion Space Defense declared war on the United States of America.
