There is a final conclusion to the discussions with Iran. What is paramount however is the ability to create a solution that will float in the end. Israel is the border of how long and how much a solution should comprise.
Israel is able to negotiate. But do not pressure mr. Netanyahu too much, he is already under a lot of stress. So be honorable and fair, that will lead to a lasting peace, because that is the goal.
Concerning EU and the peace talks, I would not carry too much interest in it. EU is not the best of partners. Too embroiled in corruption and unfairness. Keep the final goal in your focus; to make peace.
Do it gently, with all hands on the table.
G-d bless the mighty land of the free, and the blessed light bringers.
