When invader becomes the liberator…

Which country of the world and what groups are famous for their propaganda and for being able to persuade people with an ideology? But it nevertheless is a very effective method of conquering a country to persuade them you're not a conqueror you're not invading, you're not an aggressor, you are their friend and you're liberating them!
If it's Russia in our Western newspaper, it's always aggression, invasion and colonialism! But if it's one of the Western friends, the US or France or somebody like that, "Oh, well that's just intervention to protect the people and to liberate them and guarantee democracy, etc….!" You mustn't say the US ever invaded any country! That's not invasion, that's a mere protective intervention!" The US has no ideology left.
