These ships will probably be sunk and the “fun” will begin. Obama is an incompetent Marxist and has no clue as to why this is happening and how it is directly related to his appeasement policy.
Consider the possibility that Iran would take on board a number of peace activist including a former congresswoman and then torpedo the ship themselves as it approached Israel’s waters. After all, their objective is to mobilize world opinion against Israel and to isolate her from her few remaining supporters. They have no concern for the lives of a the few useful idiots on board and who would believe a denial of responsibility by Israel.
