Removal of India's nuclear no first use policy (NFU) will be more deterrent

I was reading about the policy and China and India are the only countries that have this policy. Rest of all nuclear states have rejected it.

Don't you think us abandoning it would be better? It is almost saying we wouldn't hit with our best weapon unless we get hit first. Having the policy makes the enemy think that they can wage a conventional war without much consequence because India would not use its best weapon until forced its hand.

Removing that policy would make the neighbouring countries (esp Pak) to be more cautious before they even think about starting a war. Although removing it might have some negative consequences such as sanctions., historically, we have always shown great restraint and always went for peaceful methods as much as possible. So, I think removing this policy is in the best interests of the nation.
