The RAF put it this way,
We don't count on a spontaneous anti-fascist mobilisation as a result of terror and fascism itself .....
And we know that our work produces even more pretexts for repression, because we're communists - and whether communists will organise and struggle, whether terror and repression will produce only fear and resignation, or whether it will produce resistance, class hatred and solidarity . . . depends on the response to repression. Whether communists are so stupid as to tolerate such treatment ... depends on this response.
What is revealed completely in this quote is the absolute arrogance of these groups - "Sure we're hoping for a radical response to the state repression we bring down on your heads, but if that doesn't occur, well, that will go to prove you are all stupid." They ignore the actual conditions, like all guerrillas, demanding that everyone else miraculously achieve their "advanced" consciousness, when, as has already been shown, their ideas are superficial and without value and merely a rallying cry for a massacre.
The reason for the occurrence of this ugly strategy derives from the limitations of urban guerrilla warfare. Since they depend on armed action for their existence, all guerrillas can only develop their struggle by escalating their engagements. If they do not they will be forgotten. Dynamism is everything. But rural guerrillas can do this by establishing and expanding their territory of action - liberated zones. They can choose to take on army formations according to their situation. But urban guerrillas can hold no territory, for to attempt to hold a neighbourhood or building is to take on the entire armed might of the city. In any engagement the size of army forces cannot be ascertained since they can arrive in minutes.
Urban guerrilla warfare must become terrorism in order to develop. There is no other avenue for escalating the struggle. Furthermore the warfare cannot stretch out indefinitely without withering away. This is the appeal of the polarisation and militarisation of society strategy. It is the ultimate in manipulation - an intentional attempt to create suffering among the people for the ends of the guerrillas who assume that they know best and that the people will be better off in the long run. Of course the strategy usually results only in repression.
