This invasion is carried out by two different groups: the Russians/Iranians, and the Central Caliphate. At this time, the Central Caliphate is in control of most of Iraq and has wiped Syria off the map. With its growing power, it decides to absorb Iraq before Iran has a chance to, and both forces attack Baghdad on the same day. The battle ends with a full Iranian victory and annexation of Iraq and the systematic imprisonment of all Christians. This severely weakens the Central Caliphate, wiping out most of its manpower, and puts the United States in a much safer position. Putin is counting on the United States crippling Iran at some point during the war so he can conquer it and give it to China without violating any treaties or using too many resources. This invasion is generally accepted as the day the conflict escalated into a world war. This is the most brutal and bloody battle yet in the war, and Christie's embarrassing failures here make the world begin to see the United States as a joke. His approval rating dropped dramatically after this battle.
