been thinking about the humans darkening the sky to win the war with the machines, I don't quite buy that notion that was the whole plan, as we see when neo went above the clouds what happened to the sentinals and bombs that followed, they were all zapped along with niobe's ship
and thinking that zion the last human city is underground deep into the earth, why? the machines recreated the last human city like it was before they destroyed it, but the why was the last human city underground? if darkening the sky was to be humity's best bet, why build a city under ground?
my theory is darkening the sky was not the plan, creating a world wide EM field, and building a base deep within the earth to shield themselves from the EM field was the plan, however the plan never came to a conclusion, I believe the plan was to create the em field and shield themselves from it, and to bring that em field down to fry all the machines
