If you give your dialog a known ID then you can look it up using jquery (e.g. $('#mydialog') and close it via script on the remote page. The only issue might be getting JS to be evaluated when the remote page is loaded into the dialog.
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.
