In Malaysia, if you are wishy washy, you will be washed off shore.
To be an effective PM in Malaysia, you would have to have a steely determination.
At times, you would also have to be somewhat dictatorial...especially in a country which is composed of a multhi ethnic group with each group trying to exert its own influence.
If you are weak, you as a prime minister, will be bullied into submission by the various groups. You would have to have a strong mind and a stronger determination going doggedly after correct policies.
