This important question is addressed in this well-documented and sensational film from Palaestra Media:

For many, the film’s conclusions will be disturbing, but that does not make the film any less important – on the contrary! The truth can often be uncomfortable, especially if it challenges one’s accepted worldview. But if the European peoples are to have any hope of saving their countries, cultures, and peoples from certain doom, they must find the courage to face the harsh truth and draw the necessary conclusions. No battle can be won if one cannot or will not recognize who the enemy is! Watch, understand, and share!
