What if Hindutva groups were to enter your country and take the law into their own hands?

Previously, Hindutva extremists volunteered to support Israel in its attacks on Palestinians. Later there were accusations against the Indian Hindutva-led government for its involvement in the killing of Canadian citizens inside Canada. Now, Hindutva Terrorists are seeking to cross into Bangladesh to protest and demand the release of a Bangladesh Hindutva Supporter, Chinmoy Krishna Das, from the Bangladeshi prison. It would be no surprise if, in the future, these groups attempt to enter other countries, and disrupting peace and stability wherever they go.
