The Aztec empire fell because of the way they built their empire and geography. In my opinion, it was bound to fall at sometime. I mean, they were in a lake they could be easily ambushed. I don't think they suspected that they would ever be invaded.  The Spanish came which is another big threat that made the empire fall. Hernando Cortez, led the journey to Tenochtitlan; him and his crew were very shocked when they first saw the city. At first the Aztecs suspected that they were gods. But soon they figured out their evil plane=s and had planned to attack them but it was too late.

 I think L.A. is has a good geography. We are near the ocean has an airport nearby, the LAX airport. If someone tried to invade us I think we would do survive. Los Angeles, we would be able to escape by sea if we needed to. It would still be difficult though but we could still maintain our city, I think. We could maintain unless aliens come and plot to take over our world. LIKE THAT COULD HAPPEN!?!?!?!?
