The strategy of the criminals in charge is mainly the centralization of power to eventually form a One World Government. The European Union is a good example of how to slowly boil the frog and make nations hand over their sovereignty to a superstate, which was unthinkable after the Second World War. Because their strategy is so obvious, I too came to the conclusion that decentralization is the way to go.
If you want to decentralize power, it's essential to understand the power structure. From top to bottom the structure looks something like this:
BANKS > MEDIA > POLITICIANS > PEOPLE.
Most people don't realize that the media, firmly controlled by the banks, is above the political class. Big Media creates public opinion and is able to make any politician rise or fall. The media and public opinion are the Achilles' heel of the system. We can't buy banks but we can create media and influence public opinion, locally even more easily than nationally. Politicians, wanting to decentralize power, supported by a powerful local alternative media would have the best chance to bring real change.
Secession and direct democracy would be great tools for decentralization. In a direct democracy, a majority could step by step create a voluntarist society, but it will only work in a community with well educated people and high moral values, who understand the relation between rights and responsibilities and are willing to fight for their sovereignty.
