I will only offer a personal opinion.

Psychological warfare is the activity involved in waging a war or creating a conflict using only mental constructs, such as psychological obfuscation and deception, rather than weapons of war.

Of the two worldwide Wars, the 2nd is the only that fee Britain in terms of any which you have listed - financial. WWI somewhat did no longer start up "the decay of the Empire" thinking the Empire reached it somewhat is greatest element in 1924. It replaced into no longer politically or psychologically broken after the two (even regardless of the undeniable fact that submit WWI the outcomes of mechanised conflict were introduced sharply into concentration), it nevertheless held it somewhat is status whether that replaced right into a sprint bruised after WWII; and morally it replaced into held in intense regard and massive admire using fact it replaced into the only ecu united states of america that had sacrificed it somewhat is financial potential and skill by combating on my own for a protracted era for democratic rights and freedom in WWII regardless of having the opition of no longer getting in touch interior the conflict in any respect. Had Britain stayed out of WWII (as Hitler needed when you consider that he had very lots of admiration for the British) then their financial device could be a ways extra effective than it somewhat is as we communicate. So in all honesty Britain (nor brititan) replaced into no longer left a giggling inventory (nor even a giggling stalk) on the tip of the two conflicts.
