JWs and others ae waiting for some outstaning declaration from the wprld that it has accomplished peace and security on their own
The JW interpretation of this always bugged me, too.
After all, wasn't the whole challenge in the Garden of Eden all about the devil claiming man didn't need god? That we would do fine on our own? And the reason god lets all the misery and suffering on the earth - to prove we need him?
This prophecy (as the JWs would have it) essentially boils down to, god will let humans suffer indefinately to prove they need him, until they reach a point where they DON'T, then suddenly 'flip the board over, scattering the pieces', as it were, and stomping off claiming victory.
It just doesn't make sense.
Perhaps to partly address this, and to extend the prophecy 'indefinately' (as it obviously needs to be, as it will never happen), the WT has started explaining that this will be a 'false' peace and security - the nations will declare it, but it won't actually be true peace.
Of course, this allows them to continue the prophecy forever. After all, there will ALWAYS be some groups saying 'true peace' is at hand when other groups claim it is not- it's human nature.
