If you apply through the proper channels your information should be protected (although recently the head of the CIA was found to be using an aol account to send classified material, so I get your concern). If you mean can you trust that the DV lottery is a good way to insure your move to the US, no, you can't trust it as the chances of winning are minimal.
There is nothing shady, or untrustworthy about the program or how it is run. Should trust that it will continue to exist? No.
This will likely be the last lottery.
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.
