What Did Carter Accomplish?
Because he went to Hamas on the assumption that Carter's superior talking skills would lead to peace between Israel and Hamas.
Carter is senile if he thinks that talking is the key.
The key is for both sides to want peace more than war.
When Carter brokered peace between Egypt and Israel, success came not from Carter's talking skills but from Egypt's strong need for peace.
Hamas does not want or need peace. They need war. War is what keeps them in power. Hamas has no skills for managing a peaceful Palestine. They can only arm young men, put black ski-masks on their faces and march them off to suicide. They will settle for nothing less than the utter destruction of Israel. Israel can not negotiate while its own destruction is goal of the other side.
Carter is a senile fool.
