Via a great article in The Telegraph, you can see a link to an interview with nutcase Alice Walker who will be on the US flotilla vessel called "The Audacity of Hope."
In the preface to that interview we find the exact contents of what the moonbat Americans and Canadians will be bringing with them to Gaza: letters from Americans to Gazans.
And from looking at the web page of US to Gaza, which is sponsoring the ship, we find out that the letters have already been emailed to Gaza for Gazans to make a public display out of them.
I'm sure that the starving Gazans will chew on the letters thoughtfully.
