I heard on CNN that it would take 250 Navy ships to patrol the entire area. On a talkshow, I heard an expert in Maritime shipping say these cargo ships are not armed because they have a special aggreement with various nations. They get passage if they don't carry weapons and pose a threat to any nation.

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.
