Israel's defence ministry sought to "clarify" controversial comments it made last week criticising the Iran nuclear deal and likening it to the 1938 Munich agreement with Nazi Germany.
The defence ministry said in a statement on Monday: "Friday's statement was in no way intended to draw comparisons, historical or personal. We regret if it was interpreted otherwise."
"The difference in Israel's position on this matter (the nuclear deal) from that of our close ally, the United States, in no way detracts from our deep appreciation for the United States and for the President of the United States, for their tremendous contribution to Israel's national security."
On Thursday, US President Barack Obama defended the landmark nuclear deal which was signed in July 2015 between Tehran and six world powers led by Washington.
The next day, Israel's defence ministry, led by hardliner Avigdor Lieberman, slammed Obama for defending the accord with the Jewish state's arch-foe, comparing it to the deal that allowed Nazi Germany to annex parts of then Czechoslovakia.
Netanyahu the same day repeated his country's rejection of the nuclear deal but stressed that Israel and the United States remained great allies.
