This type of question makes no sense but I'll answer it. If the United States is attached, they should colonize and make Canada and Mexico apart of the United States. They should respond by expanding the United States. This will allow the United States to control, manipulate, use and abuse the resources of the Canada and Mexican land.
Explanation:
This is the only way and only thing they do, if they are attached. It's human nature.
I would go with option B. Formally explain something important. It seemed to me that he was trying to get his point across, while still having a respectful attitude. I hope I could help!
