For me, that's the différence between a nationalist and a patriot: the nationalist thinks their country is the best, the patriot wants the best for their country. A patriot will see the flaws in the system and will try to correct them for the benefit of the community. A patriot will be happy when other people will want to join the community to make it better, or to change it. A patriot is happy when the community evolves, and will work for it. A patriot can be a foreigner initially. Doesn't change anything. The nationalist cannot accept change. Therefore, they don't accept anything that can make their community evolve. They don't realize their country changed in the past, they idealize a vision completely unbalanced of history and cannot see the flaws in the system.

Unfortunately today, the patriot is a nuisance and the nationalist a useful tool for the nefarious people which wants just more power and more money.

It's easy to sell something to someone who thinks nothing should change, it's hard to contempt someone who wants to change a system.
