- Diplomacy has always rested on two pillars : Institutional memory and individual craft. Elaborate. (Answer in 250 words)
Introduction
Diplomacy is a profession with an archive and a performer. The archive supplies continuity, precedent and legal position; the performer supplies timing, judgement and the ability to make the other side move.

Body
1. Craft defined: Ernest Satow's Guide to Diplomatic Practice (1917) called diplomacy the application of intelligence and tact; Nicolson's Diplomacy (1939) listed truthfulness, precision, calm, patience and loyalty as its professional virtues.
2. Memory as codified practice: the Vienna Conventions on Diplomatic Relations (1961) and Consular Relations (1963) turned centuries of usage into binding law, and Article 102 of the UN Charter makes treaty registration an act of institutional memory.
3. Memory as leverage: archival and technical files carried India's case in the Bay of Bengal maritime award with Bangladesh (2014), and sustain its positions on Sir Creek and the Indus Waters Treaty (1960).
4. Craft as breakthrough: Talleyrand at Vienna (1815) turned a defeated France into an arbiter of the settlement; Kissinger's shuttle diplomacy (1973-75) built disengagement out of a stalemate no brief had anticipated.
5. The pillars need each other: craft without memory yields summits with communiques and no follow-through; memory without craft yields immaculate briefs that miss the opening.
6. The Indian tradition: Kautilya's Arthashastra grades envoys by the discretion entrusted to them and pairs the duta with the sixfold policy — exactly this combination of standing doctrine and personal skill.
7. Present strain: leader-level and public diplomacy compress deliberation, as the informal summits at Wuhan (2018) and Mamallapuram (2019) showed — high craft, thin institutional record.

Conclusion
The two pillars are load-bearing only together. States that professionalise memory but starve talent become rigid, and those that rely on personality find their diplomacy expires with the diplomat.
