That would be fun if I were in charge :
1) Media control, the first thing to do if in order to avoid riots, meaning trying to preserve civilization as we know it. Internet would disappeared as it's too dangerous in my opinion, only radio and television would stay "online".
2) Army and police fusion. Strong links between army and schools.
3) Forbid any personnal car.
4) food/water/energy use limits, preserving the grid would be a priority. A/C and electric heating forbidden.
5) birth control.
6) concentrations camps for people threatening the country, people who would critisize army, police, state or politics in charge would be considered as terrorists.
7) Slowly explain the awfull situation on medias, awfull meaning peak oil and not the first 6 points I presented here ;-p.

Huge and perpetual meeting with as many as possible countries on the planet to organize a new kind of economy, at least to avoid world war 3 which would lead us quickly to Olduvai.
I know my program looks frightening, but I definitally prefer 1984 than Mad Max. It's too late to expect capitalism or technology to create some starwars fantasy out of our situation.
