Left front are chinese agent . Only one country had indian influence that was Nepal even that is under now almost under chinese control so there is one more front to counter CPM OR CPI never said any thing about it. so India had no option other than to make strong alliance to counter chinese threat. if you want to know about Sardars you must read history who fought for the country, for ur information i can tell you afgans stopped robbing TEMPLES and snatching HINDU women only when these foolish sardar came to power in north india some great RAJPUT was used to let them humiliate india to save their own skin and their tinny empires . So dont suspect Sardar Patriotism
