MIAMI (CBSMiami/AP) — While he has only indicated at this time that he is looking into a possible Oval Office run in 2016, former Gov. Jeb Bush set himself apart from his family during a speech Wednesday in Chicago.

Bush said that “there were mistakes made in Iraq” during his brother’s administration, offering the critique during the speech on foreign policy.

Speaking to the Chicago Council on Global Affairs, Bush said during a question-and-answer session after his speech that intelligence about Saddam Hussein’s possession of weapons of mass destruction was not accurate, and the U.S. initially failed to create an environment of security in the country after removing the Iraqi leader from power.

But Bush praised former President George W. Bush’s decision to “surge” troops into Iraq in 2007, which added roughly 20,000 troops to the American forces in the country in an effort to improve security. He called it “one of the most historic acts of courage politically” of any president.

The surge was “hugely successful,” Bush said, and it created a “a fragile but more stable situation” in Iraq that President Barack Obama could have built on during his term in office.

Bush offered harsh words for Obama’s foreign policy during the speech, calling his administration “inconsistent and indecisive” and one that has led the U.S. to lose “the trust and the confidence of our friends.”

“The great irony of the Obama presidency is this: Someone who came to office promising greater engagement with the world has left America less influential in the world,” Bush said.

Bush acknowledged during the speech that his views about America’s place in the world will often be compared with those of his brother and father, former President George H.W. Bush, adding he is “lucky” to have had family members who have “shaped America’s foreign policy from the Oval Office.”

“But I am my own man — and my views are shaped by my own thinking and own experiences,” he said. “Each president learns from those who came before — their principles, their adjustments.”

The older Bush brother finished his second term in 2009 amid an unpopular war in Iraq, an economy in freefall and with a majority of Americans disapproving of his job performance.

Among donors, Jeb Bush has noted a strong family and religious bond with his older brother, but has also said they are not clones and have differences common among siblings.

Pundits have said Bush needs to portray himself as more conservative, to deal with a moderate label that an increasingly right-leaning Republican electorate may have attached to him.

Bush hit on some hot button conservative topics in his Chicago speech.

“The big things we need to fix is how we regulate, how we tax, and how we get our fiscal house in order,” Bush said.  He said in dealing with ISIS and expanding Islamic terror, the United States needs to be “engaged,” but added, “It’s the responsibility of the Arab world to step up, to fight this.”

Even as Bush appears to be courting a more conservative crowd, a poll released Wednesday shows him trailing a noted right winger.  The CNN/ORC poll shows Bush trailing the very conservative former Arkansas Governor Mike Huckabee by five points, and neck and neck with the uber conservative Rand Paul.

Bloomberg Politics Managing Editor Mark Halperin, visiting Broward College on Wednesday, said Jeb Bush has no problems money can’t fix.

“The biggest thing is fundraising.  He’s going to dwarf the rest of the field,” Halperin said.  “If he can raise enough money, get his message out, he’ll be one of the strongest candidates.  I think right now he’s the strongest candidate.”

Ahead of the speech, Bush aides also released what they called a preliminary group of experts who will provide him with foreign policy advice. They included familiar names, such as James Baker III and George Shultz, both secretaries of State under President Ronald Reagan; former Homeland Security secretaries Tom Ridge and Michael Chertoff, and former Deputy Secretary of Defense Paul Wolfowitz, all three of whom served under George W. Bush.

The list also included some lesser-known names, such as Meghan O’Sullivan, a former national security adviser to George W. Bush, who now teaches at Harvard and is seen as key to Jeb Bush’s idea of lessening U.S. dependence on Middle East energy.

Bush aides also confirmed late Tuesday that former Minnesota Rep. Vin Weber, a senior policy aide to 2012 GOP presidential nominee Mitt Romney, was advising Bush.
