What is a far-right nationalist?

It is to stick to the extreme position of one's own nation, even to an extreme degree, such as thinking that one's own nation is the best and rejecting other hostile nations. In the past, it was manifested in invading other countries for its own interests, such as Germany and Japan during World War II. At present, it is manifested in the rejection of foreign immigrants. For example, some extreme right-wing political parties in France have long advocated excluding foreign labor immigrants! ! ! !
