Zunes correctly states in the first graph of the first article, (quoting directly from Chomsky): "There are still some real discernable differences to be taken into account. Indeed, given the power the United States has in the world, even minimal differences in policies can have a major difference in the lives of millions of people."
As far as the differences in their Iraq track records and choices of foreign policy advisors on their respective teams are concerned, Zunes notes:
Perhaps the most important difference between the two foreign policy teams concerns Iraq. Given the similarities in the proposed Iraq policies of Senator Hillary Clinton and Senator Barack Obama, Obama’s supporters have emphasized that their candidate had the better judgment in opposing the invasion beforehand. Indeed, in the critical months prior to the launch of the war in 2003, Obama openly challenged the Bush administration’s exaggerated claims of an Iraqi threat and presciently warned that a war would lead to an increase in Islamic extremism, terrorism, and regional instability, as well as a decline in America’s standing in the world.
Senator Clinton, meanwhile, was repeating as fact the administration’s false claims of an imminent Iraqi threat. She voted to authorize President Bush to invade that oil-rich country at the time and circumstances of his own choosing and confidently predicted success. Despite this record and Clinton’s refusal to apologize for her war authorization vote, however, her supporters argue that it no longer relevant and voters need to focus on the present and future.
Indeed, whatever choices the next president makes with regard to Iraq are going to be problematic, and there are no clear answers at this point. Yet one’s position regarding the invasion of Iraq at that time says a lot about how a future president would address such questions as the use of force, international law, relations with allies, and the use of intelligence information.
As a result, it may be significant that Senator Clinton’s foreign policy advisors, many of whom are veterans of her husband’s administration, were virtually all strong supporters of President George W. Bush’s call for a U.S. invasion of Iraq. By contrast, almost every one of Senator Obama’s foreign policy team was opposed to a U.S. invasion.
