The communists have never been faithful to India. During world war II, they supported the british(a stand opposed to that of Gandhi and other natinalistic leaders) because Josef STalin was with the allies. During the chinese agression, they openly supported China. Today they are forcing the government to go soft on naxalites because they belong to their own creed. The communists in power are a threat to the nation as they could leak sensitive defence secrets to China. BAN THE COMMUNISTS.
