His statement comes just days after Foreign Secretaries of India and Pakistan held talks in New Delhi on Feb 25.
Speaking to a news channel, Saeed said, "India wants war... If India is not prepared to hold talks, Pakistan will have to fight a war at all costs."
When asked about India's accusations about his involvement in masterminding the Mumbai attacks, Saeed replied, "Let India prove it in any court, I will be ready to accept everything."
To another question on whether people should go to Kashmir for 'jehad' against India, he said there was "no doubt" in his mind that this should be done.
He also said he had no doubt that the Pakistan government is "cowardly."
