Alright..."take a look" with the confrontation with France over the Sudan, no warefare was made, the brittish offered compensation for Sudan in exchange for France's right to Tunisnia and some west coastal ports. It's exactly what I was talking about.
And what I mean by defeating a nation is a nation on at least semi equal terms (having the use of gunpowder or something...) And actually 'conquering' or at least occupying the nation, not just interrupting their overseas trade like in the opium war or Napoleanic wars.
What you say about not being able to be touch by any competitors is simular, but not really true, about most world powers. No one could've touched Rome in it's golden ages, and no one could touch the USA today. Mainly because no one would want to go through all the trouble of doing so, except in extreme cases like the world wars or 9/11.
Rome was still very much a world power for what they considered their world. Britain had just as much say in what happened in the USA as China did to Rome. By the time of the 19th century technology in general allowed westerners to perform at a much higher scale in terms of imperialism and growth. The western Europeans made sure that the true victors in all the imperialism conquest would always be a European, not a native race. Just as Any other European could not be touched, Britain couldn't of been either. Up until the world wars, airplanes, and nukes anyway.
Put downs once again?
