DAR ES SALAAM, March 30 -- NATIONS are not built in a moment. They are shaped over time through discipline, sacrifice and deliberate choices. Roads are laid incrementally.

Institutions are strengthened step by step. Social services expand gradually until their benefits become embedded in everyday life. Tanzanias development story reflects precisely this kind of steady accumulation.

To place these gains at risk through instability or division would not only be shortsighted, but profoundly costly.

Over the past two decades, Tanzania has maintained relatively strong and consistent economic growth.
