What is the abbreviation for the four instruments of national power?

• A. PDME
• B. DIME
• C. MIDE
• D. EMID

Answer: (B)

The four instruments of national power are diplomacy, information, military, and economic power. The abbreviation DIME comes from the initial letters of those four elements, giving a concise way to reference how a state can shape outcomes by combining diplomatic engagement, information operations, military capability, and economic tools. This shorthand is widely used in planning and doctrine because it reinforces that national power rests on more than just force—it’s an integrated approach across all four levers. The other letter sequences don’t reflect this established grouping, so they aren’t used as the standard way to refer to the instruments.
