It occurs to me that the cartels are derived from CIA power, and the disruption of Mexico is being effected to prevent that CIA power from being surmounted by the government of Mexico, which competes with the cartels for political control. [edit: both the CIA and Mexico claim authority to prohibit sovereign people from determining themselves which substances they can consume, and this prohibition similarly degrades society globally, being imposed in Ecuador, Colombia, and the USA no less than elsewhere, allowing criminal imposition of authority over society that is clearly and obviously horrifically degrading civil society with the violence competition between cartels, within cartels, and between governments and cartels causes. /end edit] Cuba represents the strongest infliction of that CIA power against a jurisdiction, effected through commercial mechanisms with the results observed. While these powerful actors cannot be directly opposed, they are necessarily focused each on the other, and people remain hapless as long as they remain dependent on centralized polities.
Adopting decentralized means of production can enable the people to reduce their dependence on those polities competing to control the population they both intend to reduce and maintain dependent on the competing polities. I know your heart is for your people, and also that you recognize humanity, and not only those confined to a geographical region, are people you have commonality with and care for. It is this same humanity I have the same commonality with and share that human concern for. This is why I have shared some of the decentralized means of production with you I have learned of, because adoption of these means of producing necessities are not dependent on polities focused on international competition to control jurisdictions and their people, whom are left unserved by polities expending their resources on that competition.
Aquaponics requires no electricity to implement in it's simplest form, being merely a 55 gallon barrel of catfish fed table scraps from which water is manually dipped with buckets to hydroponically feed crops that cleanse the water that can then be returned to the catfish. A biofilter is required to fully cleanse the water of pollutants and achieve 100% reclylability, but I am not convinced Cuba faces such a dire water shortage that the provision of water suitable for catfish (far lower than necessary for people to consume) is out of reach.
Graphene ink can be printed on recycled PET beverage containers to create DIY solar panels, and graphene is just carbon, ridiculously common and inexpensive that can be transformed into graphene inexpensively (although technically demanding). Concrete doped with carbon black (very technically simple, and equally common) using salt water as an electrolyte can provide supercapacitor storage of electricity. These three advances in decentralized means of production can liberate people from dependence for these critical necessities that extant polities are failing to provide, and that are causing people to suffer the lack of.
I have provided links to these technologies in previous comments to you, and I hope there is some action underway to adopt them where you and people you care for are suffering their lack. I do not mention independent means of securing people from violent oppression in order to not cause any danger of suppression to anyone concerned, but technological advance in every field of industry today advances decentralized means of production as the most economically productive means available. The most advanced technology is the most productive technology, which is why it replaces obsolete means continually. As this replacement is occurring across every field of industry simultaneously today, a clinal boundary is being transcended that will globally transform civil society and profoundly reward merit in adoption of independence from warring polities that I hope you and yours will exemplify.
Thanks!
