It is a verbal wrestle, not a physical one. "Wrestling" = "arguing".

Some people want to talk about the problems in developed countries. Others want to talk about problems in poorer countries. They will spend more time deciding (wrestling over) what to talk about than solving problems.

Hi Shana, In English, when not specifically referring to the sport of wrestling we usually use the verbal phrase "to wrestle/wrestling with (over)" and not simply wrestle/wrestling. Here are a few examples: -Before finally asking for help, I always wrestled with expressing my inner feelings. -Since I don't have good role models in business, I often wrestle with figuring out how to be successful. -I was wrestling over the direction I should take my business until I saw the results of the study that the consultant conducted. I found a definition of wrestle with that would apply pretty well: To try very hard to deal with a problem or to make a difficult decision To better understand this use of wrestling it might be helpful to understand the basics of wrestling. To win at wrestling, you will have to compete (fight) vigorously against your opponent and it will most likely go multiple rounds, (possibly without a winner.) Wrestling endlessly over, in your example, basically means they will be fighting and arguing forever. I would envision debate to be far more civilized or structured, which is likely why they chose the more evocative phrase wrestling endlessly over which allows you to visualize the difficult journey to resolving the problems.
