By December 22, 2014, the war was at a near standstill with Chilean forces retaking the southern parts of the country and most of East Falkland but were still unable to push the invaders back into Argentina.
The Argentinian military high command had planned for a large force to push into the stronghold in Santiago to take place on Christmas Eve. After days of preparing a large infantry and armored force, the planned attack was given the go ahead and the Battle for Santiago began once Argentinian forces broke though the Chilean/CDS stronghold outside the city.
As soon as the Argentinian Army entered the city, intense urban combat took place the likes of which were unseen since the Americans fought the Confederates at Pittsburgh, with the Chilean/CDS forces having advanced training on their side and the Argentinians numbers, the battle went slowly as both sides tried to tire out the other with nonstop fighting. By December 31, half the city was in the hands of the invaders, President Bachelet (who has since moved to Iquique) called General Anaya to warn him that if Argentinian forces within Santiago did not lay down their arms at once, he would be forced to allow the use of WMDs. The General, knowing the Americans would never superbomb an ally or risk nuclear fallout reach the neutral nations, called Bachelet out on his bluff and refused.
Approximately ten minutes after the call, Sarin gas (leftover from the Second Great War) was unleashed on Argentinian forces in the city killing a majority of the infantry, who had no protection from the gas. The remaining enemy forces surrendered soon after, fearing another gas attack. After hearing of the gas attacks, General Anaya, who was described as "steaming and fuming like the fires of hell" ordered an immediate response with Mustard Gas. The target chosen was the Chilean city of Río Gallegos, one of the only few that were still held by the Argentinians. When the city was gassed, approximately 4,000 Chilean citizens were killed.
Following the use of gas by Argentina, the US finally had it and warned that all responsible for the gassing be handed over and that Argentina surrenders unconditionally within 48 hours or a
real supperbombing would occur. To prove their point, the US launched a superbomb at a remote Argentinian military facility within the rainforest along with a warning that there would be more to come. As the General was about to inform the US that he would not surrender, the General was overthrown an a coup by Army officers who would rather not see their country go up in nuclear fire. The General was arrested and Argentina unconditionally surrendered an hour later.
Aftermath
General Anaya along with at least 20 other individuals responsible were arrested and tried for war crimes in a court in Costa Rica. All were found guilty with the General and 14 cohorts being hung while the remaining would spend the rest of their lives in a US military prison.
The Argentinian military would also be affected by the war. The Army could not have more than 20,000 men in service at one time, their Navy would be for nothing more than coastal defense, the Air Force would give up all fighter and bomber aircraft along with a majority of their attack helicopters, and all WMDs were to be handed over and destroyed.
In the years after the war, both sides anger towards one another would never diminish. The Chileans were angry that they never got to lay to waste Argentina the way the Argentinians did to Chile while the Argentinians hated the Chileans for taking them off the world stage and making the country weaker as a whole along with taking more of Argentina from them. Despite the Argentinian military being weaken from post war treaties, the Chileans are still improving their military awaiting the day their sworn enemy rearms and invades once again, which lead to a "Long Drum Roll" style conflict between the two countries.
