Bulk update of Drupal 7 taxonomy terms?

Since you need to update the taxonomy structure in bulk you can use - Taxonomy Manager http://drupal.org/project/taxonomy_manager Which apart from other features has.

Taxonomy Manager is the a very good module for these purposes I used it myself to tag and add vocabularies to my website that has more than 100 posts. Its interface is also very intuitive and user-friendly.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
