Ya know if the fucking British hadnt conquered all of India and most of the world maybe your point qould be sailent. If anything its a lot easier to take down regions with large populations, namely by destroying food supplies and food imports.
Oh no I meant what I said, everyone needs to eat and the fucken second you are reliant on imports for food you are at the mercy of those doing the exporting. China is turbo fucked if those food shipments ever stop, and the US navy could stop them. If memory serves me right most of the food comes from Brazil so you dont evenneed to be near China to deal that blow.
