Keep NGO's on a short leash. Shut down any media, organisation or party related to the US security state, or at least innoculate the population against them by demanding full transparency about their funding and pointing out who pays them. Mobilize the masses to show support (has worked in Cuba). Treat members of your security forces well and weed out reactionary elements.
Most important: Do not be an incompetent and corrupt prick that people are genuinely fed up with. Do good governance, even though times are tough due to US economic warfare. Be as honest and transparent as possible about the priorities you make and the scope of the problems you face and be in constant connection to the masses so you know what problems they face and how your decisions impact them.
