Zaid Ibrahim was instrumental behind the Citizens' Declaration and the campaign to save the nation from the alleged detrimental leadership of Prime Minister Najib Abdul Razak.
However, recent developments appear to have convinced the former minister that the opposition too is in dire need of rescue.
"If all we have is a hodgepodge of ambitious people who just want to be MPs, MBs or PM, then that's not good enough for an opposition party in Malaysia.
"They will always bicker and will never be able to learn from the mistakes of the past," he added in a new posting.
Zaid also lamented that hurtful allegations have been hurled at him, the most unfair of which, he pointed out, is the accusation that he is not a team player.
"But before one becomes a player, there must be a team.
"A team comprising individuals who, in their respective leadership roles, largely agree on the core issues that the political pact care about.
"The team must support each another and work together to achieve their common goals. In a good team, leaders do not sabotage each other and they do not strike deals with their enemies.
"Only then will a true team emerge, and the players must do everything possible to make it a success," he said.
In any case, Zaid claimed there is no reason for him to be a team player because he has no intention of returning to active politics.
"I write and I speak wherever I can so we can have a better government.
"What is so disappointing is that even though we have a BN government actively doing everything a good government should not do, opposition leaders - instead of being united - are busy disagreeing amongst themselves about everything under the sun," he said.
The solution, he added, is to create a political nucleus with broad agreements that are hardy and vibrant, and that enjoy considerable support.
Zaid believes that both DAP and Amanah have the criteria for the formation of a truly viable political nucleus.
"So let's get going. It matters little if it takes several more elections to succeed.
"At least the people will not be left confused or dismayed, but instead will feel genuinely hopeful about the future," he said.
