"They used to criticise our government over the government's attitude about Pakistan but what this government has achieved? This government even could not understand Pakistan's complex approach towards India," he said, while claiming that the former UPA government had also made efforts to persuade Pakistan to take action against terrorism and also asked the US about it.
