Are you stating that number of citizens = capability to control your government. 

If so, that's an argument I haven't heard before, care to say more?

The lynchpin to understanding the servility of US citizens is the Whiskey Rebellion of 1791-1794, when the Federal army of 13,000 marched against 600 tax protestors. It was at that point (only a few years after the end of the revolution) we realized we had traded one king George for another. The only ones who speak out are the ones willing to be martyrs, and US soil is drenched with their blood.
