yeah, even if the ships stop bringing stuff in this place has more than enough food to feed the people here, about the only thing maybe people would decommission a lot of grapes to put sheep and goats in, they are the most practical for the steep terraced hills

madeira exports a lot of wine so if nobody is picking it up from the bay they very likely would just let the vines fallow and have herds keep the grass down and sell the meat on the local market

it's pretty much ideal, really, i almost hope that the international trade routes sending all that wine and cakes *does* get disrupted for a few years

i think if there is any military activity around this place, the most likely is going to be keeping those undersea cables happy, something that all sides will want anyway, USA needs it to keep their africa actions running, europe needs it to stay connected to usa and south america, and china is too far away to deploy much here
