Question

which is a common tactic used in proxy wars?
encouraging opposing powers citizens to emigrate
sponsoring wars of liberation and revolutions
controlling another country secretly
buying weapons in preparation for domestic warfare

Explanation:

A proxy war involves a country supporting another group (like rebels or liberation movements) in a conflict instead of directly engaging. Let's analyze each option:

• "Encouraging opposing powers' citizens to emigrate" is not a typical proxy war tactic. Proxy wars focus on supporting conflicts, not emigration.
• "Sponsoring wars of liberation and revolutions" fits: In proxy wars, a country might fund, arm, or support liberation movements or revolutionary groups in another region to advance its interests without direct military involvement (e.g., US supporting anti - communist forces in proxy wars during the Cold War, or Soviet support for liberation movements).
• "Controlling another country secretly" is more like imperialism or covert colonialism, not the core of proxy wars which is supporting a group in a conflict, not direct control.
• "Buying weapons in preparation for domestic warfare" is about domestic preparation, not proxy wars (which involve external conflicts with indirect support).

Answer:

B. sponsoring wars of liberation and revolutions
