[Call of Duty: Modern Warfare Series] Please explain the disjointed totally inexplicable series of events that lead up to WW3?
gpt
1) The United States sponsors terror attacks in Russia, specifically the massacre of civilians at the airport in MW2. 

2) Russia calls the US out on it, The US denies involvement. 

3) Ultranationalists in Russia take power because there are no moderates to really oppose them at this point. The US was caught red handed with CIA operates murdering civilians. If the US won't admit to sponsoring attacks then Russia decides it will attack Washington and find proof itself. The goal isn't to take over the US, it is to punish the US for its actions.

4) Some other things happen. Conspiracys are revealed, friends betrayed, people set on fire. 

5) Pierce and Soap kill everyone.

6) We all collectively agree that Modern Warfare 3 never happened.
