US Border Fence Accidentally Built in Mexico

Oops. A US border fence was accidentally built on Mexican Soil. On the one hand, its never good to illegally enter another country and set up what is technically part of a military installation. Mexico has every right to ask them to remove it and seek some sort of damages for the intrusion. On the other hand, this is out in the middle of nowhere. It seems like the respective governments own most of that property and aren't using it for anything other than a border. What real difference would it make to move the fence 6 feet in one direction or another. I think the best solution would be for the US government to apologize and offer to lease the land from the often cash-strapped Mexican government for the going rate in the area. It seems like most of the land in the area is semi-arid farmland. Guessing how much farmland leases for in that area, I would say that leasing the land for maybe even 40 or 50 years would be cheaper than moving the fence. After that time both governments could reassess their positions, so to speak. Plus, Mexico would get some money out of the deal. But, of course, governments don't always do the logical thing. I'm sure this will take a long time to resolve and end up costing the United States taxpayers lots of money.
