The new Unity PA government won't recognize Israel....

There's nothing that will get Hamas to recognize Israel.

However, a statement issued by Hamas on Tuesday stated: "The political program of the unity government does not contain any explicit or implicit recognition of the legitimacy of the Zionist entity. Nor does it include any concession on Hamas's principles and positions. Hamas will continue to abide by its own program, especially regarding the resistance and the refusal to recognize Israel."
