The real issue here is religion. As long as the Queen, Privy Council and Parliament give their permission, the girl is educated, healthy, well-mannered, willing to take on a workload of royal duties, the only problem could be the religious one. Until the new laws are finalized about Catholics marrying into the family, Harry would be expected to step down from the line of succession.
His children would have to be brought up Church of England in order to be eligible for a place in the line of succession. If Harry were to wait for the new laws to be finalized, he would be able to retain his place in line of succession, his children would still be raised in the Anglican Church.
No, he would not have to renounce his claim anymore, but he would not be allowed to convert, nor could his children be raised as Catholics if they want to keep their place in the succession. There are Asian Catholics in the former French Indochina - Vietnam, Cambodia, Laos, etc.
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.
