Statement: India has been continuously experiencing military threats from its neighbouring countries.\nCourses of Action:\nI. Engage in an all-out war to stop the recurring threats.\nII. Initiate serious dialogue with neighbours to reduce tensions at the borders.

Introduction / Context:
Persistent military threats invite calibrated responses prioritizing de-escalation, deterrence, and diplomacy. Courses of action should be proportionate, feasible, and aligned with national interest and international law.

Given Data / Assumptions:

• There are ongoing threats, not necessarily active war.
• Policy options range from diplomatic engagement to military measures.

Concept / Approach:
An all-out war (I) is catastrophic, unpredictable, and rarely a first-line response to “threats.” Serious dialogue (II)—backed by credible deterrence, confidence-building measures, border mechanisms, and third-party hotlines—directly aims to reduce tensions and prevent miscalculation.

Step-by-Step Solution:
1) Reject I as disproportionate; it escalates beyond the problem as stated.2) Accept II: diplomatic channels, flag meetings, and deconfliction protocols are standard.

Verification / Alternative check:
Global practice favors diplomacy and limited, precise responses before war.

Why Other Options Are Wrong:
Only I is excessive; Either/Both wrongly suggest parity; Neither ignores useful de-escalation.

Common Pitfalls:
Equating threat rhetoric with justification for total war.

Final Answer:
Only II follows.
