The James Webb scares me. They now have put so much money and time into it that a failure would just be unimaginable. I am sure they have run the numbers but personally I am not sure if they wouldn't be better off with iterating faster and cheaper while accepting some level of risk. Maybe a failure of the James Webb would be a good motivator for a manned mission to the Lagrange point :)
