Ethnic division is a Zionist formula for breaking up countries into smaller independent units. They succeed because every country has Mir Jaffers and Mir Sadiqs. The Zionists exploit them. Therefore, all of us, including our government officials should try their best to avoid anything that accentuates ethnic feeling. President Zardari chose to speak in Punjabi on his visit to Lahore. This was a bad mistake. All government servants and officials should speak in Urdu or English. Speaking in provincial languages would only divide the people further, causing them to demand provinces based on language and ethnicity. It is essential to speak in the national language to prevent breakup of Pakistan. Islamabad should understand this. -ZAFAR ISRAR, Karachi, April 17.
