They are arrayed against every principle for which we stand. So when the Soviet leaders jail a writer, or a priest, or a doctor or a worker, for the crime of speaking freely, it is not only for humanitarian reasons that we should be concerned. For these acts reveal a regime that is afraid of truth and liberty; it dare not allow its people to enjoy the freedoms we take for granted, and a nation that denies those freedoms to its own people will have few scruples in denying them to others. If detente is to progress then it ought to mean that the Soviet authorities relax their ruthless opposition to all forms and expressions of dissent.
