How Did the 68 Movement Fail?

Before we discuss about the failure of the 68 movement, it is necessary to investigate some points to the importance of this study:
First, identifying the threatening element of this movement may facilitate identifying similar movements in the future. Secondly, the pattern used to inflict failure to this movement is still practical.

The worldwide protest of 1968 was formed based on the idea of opposing the existing order of that time. But opposing the existing order does not label any threats or danger on this movement because at that point of time, the 'free love' movement which was approved by the mass media has been against the society order of the time. The threatening element that was in the global movement of 1968 was opposing the purposes of the order of the time (and not only opposing the ruling order.)
What could stand against the 68 movement and could finally impose failure to this movement is first predicting the formation of this movement. The second one has been a realistic prediction of power and the ability of this movement, and the other is the awareness of the fact that the present order cannot compete or fight the new order model of the 68 movement.
All three of these predictions were right. The 68 movement was so powerful to eliminate its current order. Post modernism in the cultural arena, which means a period in which the cultural pattern of "modernism" is shelved but no new model, that includes certain rules and standards is substituted, started at the same time.
Thus, cultural and social decision-makers of that time have supported the idea of forming parallel movements with the 68 movement rather than supporting and defending the ruling order. Thus, the movements such as 'free love' found new supporters; the movement that despite its opposing against public order was not against its goals.
The most important feature of the 68 movement that led to attracting support for the movement was the slogan to oppose the ruling order. Thus, the parallel movements with the 68 movement by taking same slogan could grab the most important and attractive element of the 68 movement and finally win in the competition against it.
Finally it can be concluded that the pattern of use of the "parallel" theory or movements to eliminate any theory or movement that its emergence is unacceptable is practical.
