Basu made this claim at a press conference held in parliament house on Monday afternoon.
He charged that the government of India had allowed the US president George Bush to misuse the Indian soil and call for a regime change in Iran just because the Iranian government was not toeing the American line on the enrichment of the nuclear fuel.

"Bush in his statement from the Purana Qila had said that there would be a regime change and his secretary of state said that US was willing to spend $75 million dollars to effect the regime change in Iran. We have seen what kind of change America has brought in Iraq where people are being killed every day in the name of spreading democracy in the world. It has added Iran and Cuba in the list.
Cuba has a history of long association with India and it was established through a famous photograph wherein President of Cuba Castro was seen hugging former Indian Prime Minister Mrs Indira Gandhi at the 7th non-alignment summit," he pointed out.
The CPM leaders wondered why the government of India had not contradicted the statement of Bush and deplored it. " The clarification came only after the CPM built up the pressure," he said.
Nilotpal Basu wondered why the government of India was taking time to come clean on the deal between India and United States of American on the nuclear deal.
"We are being told about the deal through the media which are quoting highly place sources but the government has not said anything. I hope prime minister would come out with the details on the issue on Tuesday or Wednesday," he said.
He said that Narendra Modi government has lost its moral right to continue in office after U C Banerjee commission report has said that the Godhra train fire was accidental and not a part of the conspiracy.
