You mean Bhagat Singh. FYI he didn't murder innocent people on the streets, threaten to kill and maim unarmed poor people to gain support of people and neither did he adopt an alien ideology as his own just because he wanted to delineate himself from his motherland.
OIC is a joke; they are just a kebab-tea party meant to make each other feel relevant in the world. Name me one single geo-political achievement they have outside their own members. Nothing.
Half of them are not even interested in anything except lip service and won't bother with what is happening anywhere else. The other half don't even have a proper military to hold their own countries in one piece, let alone attack others.
You are the only OIC member who has an issue with us. Others could not care less.
GCC countries sell us oil and have military cooperation treaties with us; Turkey talks sweet to you but has robust economic and commercial ties with us, on the verge of further expansion. Malaysia and Indonesia have some of the closest strategic ties in ASEAN + India format including military training and maintenance training and support pacts between our air forces. The ex-USSR Stans send their cadets every year to train with our military and regularly vote in our favour on so many global issues. Egypt has an independent foreign policy from the mythical 'ummah' you guys talk about. Afghanistan is one of our closest friends in the region. Mozambique, Thailand and Russia are just ceremonial members and are non-Muslim and close partners of India.
The rest of them are, in Indian view, are irrelevant.
