To be diplomatic means to have the ability to handle difficult situations or sensitive matters with tact and care, so as not to upset or offend anyone. It involves managing relationships, often between countries, through negotiation, dialogue, and peaceful resolution rather than conflict or force. Diplomacy is about being tactful, polite, and skilled at finding solutions that satisfy different parties without creating resentment. It is especially relevant in international relations but also applies in personal and professional contexts where keeping peace and understanding is important.
