The real reason it was changed is because Synder felt it would take up too much time to properly introduce the squid and all of that backstory. As it was the whole Watchmen story which could easily be 12-14 hours proper was severely cut down in the 2 hrs and 45 minutes.
As for the Dr. M idea, The Russians saw the destruction of Moscow and then New York minutes after. So the idea is that Dr. M is the larger threat and is even attacking his home country so they have to band together to try and handle it. If something from the US actually went Rogue it'd be perceived as a larger threat it'd be handled as such, think about terrorist groups that are based in the Middle East. We aren't destroying Pakistan to get Bin Laden even though the general thought is that he is there and we are even working with them to try and find him. Same kind of idea....they would work with us to try and stop the greater threat.
None of this deeper level things will ever be shown in the film because there isn't enough "time" to do it. After watching Under the Hood and the Black Freighter I could see in spades how much it would have helped the general population to have those interwoven into the actual film. I really wish Synder had actually filmed everything, released an abbridged version for the theaters and given us Watchmen proper on a set of DVDs or something similar.
But, but... the alien squid could have been explained in one or two sentences, just like it was in the book! Still reeks of BS to me.
Agreed there's not enough time to do the story justice in a typical 3-hour film... which is why the argument is so strong that it shouldn't have been a theatrical film in the first place... there was just no way it was going to attract the 'general' public, it was destined for failure (in the theaters) from the beginning! I agree that putting it all on DVD would be awesome. And I will give the director's cut a chance when it comes out
