But in an apparent nod to Netanyahu ahead of key White House talks on Monday, Obama said if sanctions failed to curb Tehran's atomic ambitions, US military action against Iranian nuclear facilities should not be ruled out.
"I think that the Israeli government recognizes that, as president of the United States, I don't bluff," Obama told the Atlantic Monthly magazine in remarks published Friday.
"I also don't, as a matter of sound policy, go around advertising exactly what our intentions are. But I think both the Iranian and the Israeli governments recognize that when the United States says it is unacceptable for Iran to have a nuclear weapon, we mean what we say."
US strategy included isolating Tehran politically, sanctions and diplomacy, Obama said.
"And it includes a military component. And I think people understand that," he added.
On his way to Washington, Netanyahu arrived Friday in Canada against a backdrop of fears that Israel could unilaterally strike suspected Iranian nuclear sites.
Speaking alongside Canadian Prime Minister Stephen Harper during a visit to parliament in Ottawa, Netanyahu had tough words but was careful not to appear to be pressuring his US ally.
"I have not set red lines and we are not seeking to set red lines to the United States," he said in Hebrew.
"We do ask to reserve the freedom of action of the state of Israel in the face of threats to wipe us off the map. I think that is something that any state would demand for itself."
Tehran insists its nuclear program is for civilian purposes, but Western nations suspect Iran is trying to secretly develop atomic weapons and is close to achieving its goal.
Netanyahu says all options remain on the table concerning action on Iran, whose President Mahmoud Ahmadinejad has repeatedly questioned Israel's right to exist.
To allay suspicions, Netanyahu says Iran must dismantle its underground nuclear facility in Qom, stop uranium enrichment and eliminate all enriched material beyond what it needs to make medical isotopes or generate nuclear power.
"And when I say all the material, I mean all the material, from 3.5 percent up," Netanyahu said.
Obama warned, however, that a premature military strike could inadvertently help the Iranian regime.
"At a time when there is not a lot of sympathy for Iran and its only real ally (Syria) is on the ropes, do we want a distraction in which suddenly Iran can portray itself as a victim?" Obama said.
Regardless of Israel's role, "it would still be a profound national-security interest of the United States to prevent Iran from getting a nuclear weapon," the president argued.
He also spoke of the "profound" risks of an Iranian nuclear weapon falling into terrorists' hands, and warned of "the prospect of a nuclear arms race in the most volatile region in the world, one that is rife with unstable governments and sectarian tensions.
"And it would also provide Iran the additional capability to sponsor and protect its proxies in carrying out terrorist attacks because they are less fearful of retaliation," he said.
Israeli President Shimon Peres told the New York Times Thursday that the United States must make it clear to Iran that "all options are on the table."
"We need a total and clear commitment that the catastrophe of Iran will not create an impossible situation," Peres said, acknowledging there was disagreement over where to draw the red line that would spark military action.
Obama, who addresses the powerful American Israel Public Affairs Committee (AIPAC) on Sunday, said essentially "our goals are in sync" adding "we've got Israel's back. And that's something that I constantly try to reinforce and remind people of."
But he admitted to differences with Netanyahu, describing their relationship as one focused on business and noting their different political traditions.
Obama will briefly meet Peres – a fellow Nobel Peace Prize winner – "backstage at AIPAC," a senior US official said, speaking on condition of anonymity. There were no details on what the two would talk about.

why only talks go ahead man then we gonna see iran reaction ........
If Netanyahu and Ehud Barak, these two hotheads want to launch a strike on Iran, it's their business. and they should be on their own Obama ought to be wise enough not to have Netanyahu dictate the U.S. foreign policy. The Americans are war-weary and have no appetite for another war in another Muslim country.
No different that Iraq -- this could all be resolved peacefully by simply allowing the United Nations inspectors to do their jobs. Iran has been caught lying so many times that no one of the Security Council trusts them and it's time for them to answer all questions and give full access to the inspectors. Iran lost a generation of their youth in a war with Iraq that lasted almost 8 yrs with no victor - the same Iraqi military that the USA defeated (twice) in a few weeks.
We know that most politicians bluff Barak Hussain Obama. All mouth n no trousers n all that bro. I say bring it on. You want all the Muslims to rise in unison. We want that too. Help us unite (over 3 billion just to remind you).
Gosh the American government is unbelievable.
Another invasion, another million of dead people for the same old strategic gains, no wonder US is above all the Mighty terrorist on this globe who does terrorism in the name of spreading peace and those who retaliate against their barbarism are termed as terrorists, this is what American definition of terrorism is. Best of Luck my dear american fellows, have a happy innocent blood laden resourceful future.
I think the Americans are asking for trouble. The Iranians have the right to build nuclear weapons as much the Israelis have - the Israelis do not need nuclear weapons to initmidate and control the Middle East, as proxy, on behalf of the Zionist United States. The United States will make a big mistake in attacking Iran because the retaliations will cover not only the United States interests but also the United States itself. They will have to test the resolve of the Iranian people. My advice do not test the resolve - there will be consequences.
