According to Galtung, the US empire causes "unbearable suffering and resentment" because the "exploiters/ killers/ dominators/ alienators, and those who support the US Empire because of perceived benefits" are engaging in "unequal, non-sustainable, exchange patterns". In an article published in 2004, Galtung predicted that the US empire will "decline and fall" by 2020.
However, the decline of the US empire did not imply a decline of the US republic, and the "relief from the burden of Empire control and maintenance...could lead to a blossoming of the US Republic". Elaborating on the radio and television program Democracy Now, he stated that he loved the American republic and hated the American empire. He added that many Americans had thanked him for this statement on his lecture tours, because it helped them resolve the conflict between their love for their country and their displeasure with its foreign policy.
