Communist Goals (1963) Congressional Record—Appendix, pp. A34-A35 January 10, 1963
#17. Get control of the schools. Use them as transmission belts for socialism and current Communist propaganda. Soften the curriculum. Get control of teachers’ associations. Put the party line in textbooks.

#31. Belittle all forms of American culture and discourage the teaching of American history on the ground that it was only a minor part of the “big picture.” Give more emphasis to Russian history since the Communists took over.
