The United States and Poland are kicking off an international conference on the Middle East on Wednesday amid uncertainty over its aims and questions about what it will deliver. Initially it was billed by President Donald Trump's administration as an Iran-focused meeting, but the organizers significantly broadened its scope to include the Israeli-Palestinian conflict, the fight against the Islamic State group, Syria and Yemen. The shift was designed in part to boost participation after some invitees balked at an Iran-centric event when many, particularly in Europe, are trying to save the 2015 Iran nuclear deal after last year's U.S. withdrawal and re-imposition of sanctions in its self-described ``maximum pressure campaign.'' Yet the agenda for the discussions contains no hint of any concrete action that might result beyond creating ``follow-on working groups,'' and many of the roughly 60 countries participating will be represented at levels lower than foreign minister. While Israeli Prime Minister Benjamin Netanyahu and U.S. Vice President Mike Pence will attend along with Secretary of State Mike Pompeo and his counterparts from numerous Arab nations, France and Germany are not sending cabinet-ranked officials, and E.U. foreign policy chief Federica Mogherini is staying away. Russia and China are not participating, and the Palestinians, who have called for the meeting to be boycotted, also will be absent. Iran, which is celebrating the 40th anniversary of its Islamic Revolution this week, has denounced the meeting as a ``circus.'' Pompeo predicted that the conference will ``deliver really good outcomes'' and played down the impact of lower-level participation. He told reporters in Slovakia on Tuesday that this ``is going to be a serious concrete discussion about a broad range of topics that range from counterterrorism to the malign influence that Iran has played in the Middle East towards its instability.'' According to the agenda, Pence will address the conference on a range of Mideast regional issues, Pompeo will talk about U.S. plans in Syria following Trump's decision to withdraw American troops and Trump's senior adviser and son-in-law Jared Kushner will speak about his as-yet unveiled Middle East peace plan. ``We think we will make real progress,'' Pompeo said. ``We think there'll be dozens of nations there seriously working towards a better, more stable Middle East, and I'm hoping by the time we leave on Thursday we'll have achieved that.'' He did not, however, offer any details about specific outcomes. Pompeo's co-host for the conference, Polish Foreign Minister Jacek Czaputowicz, also steered clear of describing potential results. And, he made note of differences between the United States and Europe over the Iran nuclear deal known as the Joint Comprehensive Plan of Action, or JCPOA, that also exist among Washington and Warsaw. ``Poland is a part of the E.U., and hence we are of the opinion and we accept the policy of JCPOA,'' Czaputowicz told a joint news conference with Pompeo on the eve of the conference. ``We consider this to be a valuable element on the international arena.'' In a joint opinion piece published Wednesday by CNN, Pompeo and Czaputowicz said they did not expect all participants to agree on policies or outcomes but called for an airing of unscripted and candid ideas. ``We expect each nation to express opinions that reflect its own interests,'' they wrote. ``Disagreements in one area should not prohibit unity in others.'' In fact, three of America's main European allies, Britain, France and Germany, have unveiled a new financial mechanism that the Trump administration believes may be designed to evade U.S. sanctions on Iran. British Foreign Secretary Jeremy Hunt is attending the Warsaw conference, but his main interest is in a side meeting on the conflict in Yemen, according to diplomats familiar with the planning. Since Pompeo first announced the conference as a vehicle to combat increasing Iranian assertiveness during a Mideast tour in January, he has steadily sought to widen the program's focus with limited success. Despite his efforts, Iran is still expected to be a major, if not the primary, topic of discussion, notably its nuclear ambitions, ballistic missile program, threats to Israel and support for Shiite rebels in Yemen and Bashar Assad's government in Syria. On his way to Warsaw, Netanyahu made clear he believed the conference is centered on Iran. ``The focus is Iran,'' he told reporters. ``Iran threatens us on the 40th anniversary of the revolution. They threatened to destroy Tel Aviv and Haifa, and I said that they would not succeed, but if they try then I repeat that this will be the last anniversary of the revolution that they celebrate, this regime.'' The Trump administration has repeatedly denied allegations that it is seeking regime change in Iran. And yet, mixed messages continue to come from Washington. Earlier this week, Trump's national security adviser John Bolton released a short video on the anniversary of the Iranian revolution in which he called Iran ``the central banker of international terrorism'' and accused it of pursuing nuclear weapons and missiles to deliver them and of ``tyrannizing its own people and terrorizing the world.'' The video ended with a not-so-veiled threat to Iran's Supreme Leader Ayatollah Ali Khamenei: ``I don't think you'll have many more anniversaries to enjoy,'' Bolton said. Such rhetoric has prompted criticism from Europe and elsewhere but also from Obama administration veterans who have vocally opposed Trump's attempts to wreck the nuclear deal, which was one of their signature foreign policy achievements. One group of former Obama officials, National Security Action, said the Warsaw conference was little more than an ``anti-Iran pep rally'' that underscored Trump's isolation. ``We expect to see again this week an American approach to Iran that will showcase our alienation,'' it said in a statement. ``More than merely embarrassing, the administration's stated `maximum pressure' approach is incoherent, as America lacks allies willing to support such a strategy. Not a single E.U. country has endorsed pulling out of the Iran deal, unsurprising given that the Trump administration's own intelligence chiefs testified earlier this month that Iran remains in compliance.''
