Domestic and foreign policy are organically linked, not separable

Evidence

Is it domestic policies which determine foreign policy, or vice versa? In this case too, it will be necessary to distinguish: between great powers, with relative international autonomy, and other powers; also, between different forms of government (a government like that of Napoleon III had two policies, apparently—reactionary internally, and liberal abroad). — Antonio Gramsci, Selections from the Prison Notebooks, 982

Categorization

• QUESTION: The Napoleon III example is echoed in the modern observation that repressive states often project liberal self-images abroad — worth chasing as a mechanism.
• corroborated: 2 independent passages support this claim — Antonio Gramsci, Selections from the Prison Notebooks, 982
• XREF: connects to: Foreign affairs cannot be governed by fixed antecedent laws — John Locke, Second Treatise of Government, 184
