CAIRO — US Secretary of State Mike Pompeo brought the Trump administration’s anti-Iran message to Gulf Arab states on Friday, arriving in Bahrain to continue a nine-nation tour of the Middle East aimed at reassuring America’s partners that withdrawing troops from Syria does not mean Washington is abandoning the region.

Pompeo was traveling to Bahrain and the United Arab Emirates, where he will call for increasing pressure on Iran and push for unity among Gulf neighbors still embroiled in a festering dispute with Qatar. He’ll also be promoting a US-backed initiative to form what some have termed an “Arab NATO” that would bring the region together in a military alliance to counter threats from Iran.

In Bahrain, the UAE and later Qatar, Saudi Arabia, Oman and Kuwait, Pompeo will also be making the case — as he did on previous stops in Jordan, Iraq and Egypt — that President Donald Trump’s decision to pull US troops from Syria is not a sign that Washington is retreating from the fight against the Islamic State group.

US partnerships with the members of the Gulf Cooperation Council “are critical to achieving shared regional objectives: defeating ISIS, countering radical Islamic terrorism, protecting global energy supplies, and rolling back Iranian aggression,” the State Department said in a statement released as Pompeo departed Egypt for Bahrain, which is home to the US Navy’s 5th Fleet.

But the now-2-year-old crisis between GCC members Saudi Arabia and UAE and Qatar has hampered US attempts to forge a unified front against Iran. Washington’s efforts to ease the dispute, begun by former Secretary of State Rex Tillerson, have thus far failed, and took another hit this week when the former general tasked to broker a solution stepped down.

“A united GCC is the backbone for regional peace, prosperity, security, and stability, and is essential to countering the single greatest threat to regional stability: the Iranian regime,” the State Department said.

At each of his stops in the Gulf, Pompeo will be urging progress on creating the Middle East Strategic Alliance, which would join GCC militaries with those of Egypt and Jordan to serve as a counterbalance to Iran, which they all accuse of fomenting unrest and rebellion throughout the region.

Pompeo told Fox News before departing from Cairo that there would be an international conference on Iran and the Middle East in Poland on Feb. 13-14.

Pompeo during his trip will also call for boosting efforts to end the conflict in Yemen, where a Saudi-led coalition has been battling Iranian-backed rebels in what the UN says is now the world’s worst humanitarian crisis, the department said.

UN-led peace efforts in Yemen, along with attempts to broker a political solution to the war in Syria that “expels every last Iranian boot from the country” and promoting reconciliation in Afghanistan will also be high on Pompeo’s agenda, the State Department said.

Pompeo kicked off the Gulf portion of his tour after a stop in Cairo, where he delivered a scathing rebuke of former President Barack Obama’s Middle East policies that Obama had outlined in a 2009 address to the Arab and broader Muslim world.

In a speech titled “A Force for Good: America’s Reinvigorated Role in the Middle East,” Pompeo accused the former president of “misguided” thinking that diminished America’s role in the region while harming its longtime friends and emboldening Iran.

He unloaded on the Obama administration for being naive and timid when confronted with challenges posed by the revolts that convulsed the Middle East, including Egypt, beginning in 2011. And he said the Trump administration was taking action to repair the damage.

“The age of self-inflicted American shame is over, and so are the policies that produced so much needless suffering,” Pompeo said in the speech, which was itself denounced by former Obama administration officials for pandering to autocrats and ignoring human rights concerns.

“That this administration feels the need, nearly a decade later, to take potshots at an effort to identify common ground between the Arab world and the West speaks not only to the Trump administration’s pettiness but also to its lack of a strategic vision for America’s role in the region and its abdication of America’s values,” National Security Action group, a group of former officials, said in a statement.

Pompeo blamed the previous administration’s approach to the Mideast for the ills that consume it now, particularly the rise of the Islamic State group in Iraq and Syria and Iran’s increasing assertiveness, which he said was a direct result of sanctions relief, since rescinded by the Trump administration, granted to it under the 2015 nuclear deal.

He said Obama ignored the growth of the Iranian-backed Hezbollah movement in Lebanon to the detriment of Israel’s security and didn’t do enough to push back on Iran-supported rebels in Yemen.

Since withdrawing from the nuclear deal last year, the administration has steadily ratcheted up pressure on Tehran and routinely accuses the nation of being the most destabilizing influence in the region. It has vowed to increase the pressure until Iran halts what US officials describe as its “malign activities” throughout the Mideast and elsewhere, including support for rebels in Yemen, anti-Israel groups and Syrian President Bashar al-Assad.
