I think it's very important for writers and artists generally to be witnesses to the world, and to be transparent. To let other people speak... to travel... to experience the world. And memorialize it.
Why should the Eisenhower memorial be over twice the size of WWII Memorial? Why should it be so vast as to comfortably house two Lincoln Memorials, two Washington Monuments, and two Jefferson Memorials - all six at once?
People can and do change.
