Jerusalem

AS the United Nations General Assembly opens this year, I feel uneasy. An unnecessary diplomatic clash between Israel and the Palestinians is taking shape in New York, and it will be harmful to Israel and to the future of the Middle East.

I know that things could and should have been different.

I truly believe that a two-state solution is the only way to ensure a more stable Middle East and to grant Israel the security and well-being it desires. As tensions grow, I cannot but feel that we in the region are on the verge of missing an opportunity — one that we cannot afford to miss.

The Palestinian president, Mahmoud Abbas, plans to make a unilateral bid for recognition of a Palestinian state at the United Nations on Friday. He has the right to do so, and the vast majority of countries in the General Assembly support his move. But this is not the wisest step Mr. Abbas can take.

The Israeli prime minister, Benjamin Netanyahu, has declared publicly that he believes in the two-state solution, but he is expending all of his political effort to block Mr. Abbas’s bid for statehood by rallying domestic support and appealing to other countries. This is not the wisest step Mr. Netanyahu can take.
