It also warned that if there is a guerrilla war, it will carry on for years without any gains for Islamabad.
Pakistan aims to capture the territory in the next six to eight weeks before winter snows make the going much tougher. Three previous offensives in South Waziristan since 2004 have all ended with the Pakistan Army withdrawing, leaving the Taliban in a stronger position.
Brigadier General (retired) Javed Hussain said, "The forces that the army is employing is not enough. The important thing is that we have to avoid getting into a guerrilla war because a guerrilla war carries on for years on end."
"They have to bring in more forces and make use of the geography. Guerrillas' safe havens reside in the mountains.
"In the opening moves, the army should have landed troops to secure the heights, to force the guerrillas into the valleys, where you can take them down using air-delivered and ground-delivered firepower," The Telegrah quoted him, as saying.
South Waziristan is not only crucial for Pakistani Taliban but it is also a safe haven for Afghan insurgents and al-Qaeda, making it a global hub for extremism.
