"We need to maintain a cool behaviour with our neighbours but if someone attacks us there is a need to retaliate and show our strength to them," Swamy said addressing a gathering here.
Swamy was speaking during a two-day seminar on "Continuity of Indian identity" organised by Arundhati Vashishtha Anusandhan Peeth (AVAP), a research organisation founded by late VHP leader Ashok Singhal.
"We also need to maintain a distinction between identity and citizenship. There are so many countries who allow dual citizenship but not India because here we are more particular about the identity and that is how citizenship is granted," he said.
