Based on the context of your question, I think you meant to write: "There's no hope for humanity until trash places like Pakistan, Israel, Iran and Turkey CEASE TO exist true or false?" After all, Pakistan, Israel, Iran and Turkey all exist currently.
The answer is no. Getting rid of these nations will not save humanity. Face it: We as a species are trash. Getting rid of some of the most problematic nations out there, and Israel, isn't going to give humanity much more hope.
