In the end of the book/movie 1984, Winston defiantly tells O'Brien, his interrogator, that "love will conquer hatred," which seems to imply that love hurts the Party and hatred supports the party. O'Brien even tells him that "hatred is as necessary as love, or perhaps more necessary," as if hatred were the basis of their system. Right afterwards, O'Brien tells Winston that the ultimate goal is to get him to love the party and Big Brother, something of a contradiction to the preceding conversation.
This illustrates something that should be very obvious to anyone who isn't a hippie, which is that "the system," and really, any system, relies on love much more than it does hatred, that any hatred that it attempts to instill is calculated to increase love of the system. That is why it does not matter which country Oceania is at war with; what matters is that the people love the system.
Generalizing this basic idea, it seems that anyone proposing to instill "universal love" is also trying to pave the way for Orwellian government, and vice versa. Stalin, Napoleon, Hitler, all these men talked of universal this and universal that. And of course, Christianity played no small part in inspiring the West's will to conquer. Not even the Dali Llama is immune; his book "The Compassionate Life" talks about how his ideal is for a "benevolent" world government that controls all access to weaponry.
