The End of Occupation Amongst Humanity
The best way to hit back at an occupier is to target their economy.
The police and the military are just there to protect the economy and stability within the occupied territory.
The real thing that motivates an imperial power is the economic benefits that they receive from the occupation.
Hence, how Gandhi made salt over the British salt-makers.
Make the occupation more expensive for the occupiers than it is worth to them, and you can achieve victory without violence and without bringing the excessive violence that comes from attacking police or military establishments.
Think about it.
