Are young people enlightened enough not to fight another World War?

WWI and WWII saw massive participation from the younger generations which resulted in massive casualties and deaths on all sides that fought. In the early to mid 20th century the younger generations had a lot of faith in their leaders and politicians, which I don't think is existent today. I would like to think that younger people of today wouldn't do the bidding of disenfranchised leaders. Do you think the younger generations of today would participate in such an atrocity or do you think they would be wise enough to say no?
