Weekly quiz #4 who said this?

Tell me who uttered these wise sayings. Where a person re-quoted another person's quote, you are allowed either but you get a bonus point if you get both (or all).

I thought I'd dial down the difficulty level a bit this week! Hope you all appreciate that.

Quote 1: "All warfare is based on deception"

Quote 2: "I am become death, the destroyer of worlds"

Quote 3: "For 10 years we in the Tory party have become used to Papua New Guinea-style orgies of cannibalism and chief-killing"

Quote 4: "Democratic societies are unfit for the publication of such thunderous revelations as I am in the habit of making"

Quote 5: "I am fond of pigs. Dogs look up to us. Cats look down on us. Pigs treat us as equals"

Quote 6: "Who controls the past controls the future. Who controls the present controls the past"

Quote 7: "If everyone demanded peace instead of another television set, then there’d be peace"

Good luck!
