In excerpts of a speech to be delivered on Wednesday to the Republican Jewish Coalition, Romney will also declare that Iranian President Ahmadinejad "should be indicted for the crime of incitement to genocide."
Romney accuses President Obama of having called on Israel to "adopt indefensible borders," having "insulted" Prime Minister Benjamin Netanyahu and having been "timid and weak in the face of the existential threat of a nuclear Iran."
"These actions have emboldened Palestinian hard-liners who now are poised to form a unity government with terrorist Hamas and feel they can bypass Israel at the bargaining table".
"Obama has immeasurably set back the prospect of peace in the Middle East".
"As President, my policies will be very different.
"I will travel to Israel on my first foreign trip. I will reaffirm as a vital national interest Israel's existence as a Jewish state. I want the world to know that the bonds between Israel and the United States are unshakable. I want every country in the region that harbors aggressive designs against Israel to understand their quest is futile and that continuing it will cost them dearly.
"The ayatollahs will not be permitted to obtain nuclear weapons on my watch. A nuclear-armed Iran is not only an Israel problem, it is problem for the United States and all the decent countries of the world. Our friends should never fear that we will not stand by them in an hour of need. Our enemies should never doubt our resolve."
