Mitt Romney says any public differences between the United States and Israel only embolden adversaries.

The U.S. presidential candidate says it is a "basic truth" that the United States and Israel will always stand together.

Without mentioning the tensions between President Barack Obama and Israel's leaders, Romney suggested in a Jerusalem speech Sunday that the diplomatic differences only encourage Israel's enemies.

Obama has, at times, broken with Israel's leaders and called on Israel to follow through on its commitments, such as to halt building of housing settlements.

Romney says he would never criticize Israel and would be a steadfast ally to the Jewish state.
