Gulf Oil Spill, because the Israeli blockade only affects some dirty foreigners, but the Gulf spill affects the world's oceans.
Obviously the Gaza Raid(s) because the oil spill wasn't enough to unite the country and draw the spotlight away from the present domestic conditions. It further government control over the oil industry, like what will happen in the mid-east, but that takes time, so wait for yet another biggy.
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.
