Should the world take Iran's hope about Israel seriously?

Iran Nuclear Deal Will Be Enforced

I believe that the world should take Iran seriously, because this is another country we're talking about. Israel is a part of the world, people live there. Iran is supporting the ISIS group that has been attacking and taking over the homes of many groups of people. The Iranian leader hopes for the end of Israel. I think that we should do what we can to keep them at peace and to not go into war. If they do go into war, I think we should help Israel because we have been helping them for many years. I don't think it's right for a country to threaten another country because they don't get along. It's wrong.
