COMMENT Former deputy prime minister Musa Hitam should not just confine himself to strike-and-retreat tactics to foil expedition ‘Get rid of the incumbent’ now under way in Umno, courtesy of perennial wrecker Dr Mahathir Mohamed.

A sustained argument rather than guerrilla-like hit-and-run sorties - of which Musa is fond - is what is needed to baulk Mahathir in the latter’s campaign to replace Umno president and Prime Minister Najib Razak.

The public will be edified by a detailed exercise in explanation and would surely prefer Musa's ( right ) to the tedium of listening to inanities Umno flunkies are presently spouting in defence of Najib.
