Seriously that has to be the dumbest thing ever. So if a person from China decides to go on a killing spree tomorrow, we go to war with them? Doesn't make any sense... 
 
Seriously this game just doesn't hold up anymore. I thought it was awesome last year but trying to play the single player again... Yah I get the "story" but it's just so mind numbing. There is no shock factor when you try to shock the player every 5 minutes. 
 

Didn't... Hitler... spark an entire war?

I thought the point was that he was CIA or some other government official, so it wasn't just the act of a person but the act of a government.

How about Gavrilo Princip?

How about every fucked up dictator ever?

Year later and people are still making these threads.

You know... because COD is supposed to be realistic.  
 
And yeah man head of Gavrilo Princip? 
Sure, they were all looking for an excuse to fight each other, but it can only take one even sometimes. 

Isn't MW2 Russia supposedly ruled by Ultranationalists despite Zakhaev's demise?
 
So thus, when a CIA agent participates in a mass murder and is discovered by one of the nation's kingpins, how would one not expect the country to flip? Especially when they're receiving some backdoor kickback thanks to

" Didn't... Hitler... spark an entire war? "

If the 'person from China' was acting on behalf of the Chinese State, sure.  That would be considered an act of war.

As others have mentioned, it's kinda actually happened before. Plus it's just a game. Plot points such as these shouldn't determine whether or not it "holds up".

For a game that's meant to have no plot, no story and just be a Michael Bay experience, the amount of people who don't get MW2 is tragic, hilarious and unsettling all at once.

" Didn't... Hitler... spark an entire war? "

Don't try to make sense of MW2's plot.
 
It's not worth the effort.

in COD years, MW2 is a 10 year old game.. we're done discussing it, its ancient history

Osama did the same thing on a sunny September day.  

I'm pretty sure that one guy managed to spark WWI. You know, the assassin who killed the Archduke and his wife? And I mean literally, almost the same exact thing as what happened in MW2. 
 
Too bad there aren't any ninja edits, or people wouldn't notice my mistakes.
