I would be prepared to return the Great Muslim Mosque of Cordoba in Spain to Islam in exchange for the Hagia Sophia in Constantinople". I assume you are the King of Spain speaking in accordance with the advice of your Prime Minister and his cabinet. My personal advice to you is that the tourist potential could make it a financially attractive proposition, depending on whether you leave Haiga Sofia 'in situ' or transport it to Andalucia.
However, I would wait a year or two while the Turks are fixing it up. They seemed to have a lot of scaffolding in the place when I was there last. More.
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.
