On the account of 1, are you saying that the existence of the nation can totally exist without nationalism? As for 2, different people have different values and beliefs - I'm taking the absolute hardline stance that the existence of terrorism is unto itself enough cause to negate the existence of any nation.
As for 3, I can't disagree. The nation is one extreme, anarchy is the opposite extreme.
The point is to have a discussion, which is why I asked you to elaborate. My own answer is also yes - the existence of the nation and nationalism means the existence of terrorism.
Everyone on Earth is Bella Swan's house, in the Twilight series, yet no political leader will publicly speak this idea.
The images in the movies suggest an end of the world feel; like the Swan house exists after everything else.
The contrast of the white of the house against the stark greenery of the forest after it is suggestive. Bella's room is also transcendent.
