I think that poets can say, "What we want is for everybody on earth to wake up free from fear and with access to medicine and clean water and education." But I don't think poets have any special insight on how to get there. And the 20th century is a pretty good record of that because so many of the great poets were Stalinists: Vallejo, Neruda, Eluard, Aragon, etc. They wrote their odes to Lenin and Stalin. They glorified some of the most violent and grotesque dictatorships of the 20th century. And a lot of the ones who were not Stalinists were fascists or fascist sympathizers.
Robert HassThe record of poetry in the 20th century isn't all that great anyway. Most of the poets who weren't fascists were Stalinists.
