US-Latin American relations fell to record lows during the George Bush years, and there have been hopes – both north and south of the border – that President Barack Obama will bring a fresh approach. So far, however, most signals are pointing to continuity rather than change.

Obama started off with an unprovoked verbal assault on Venezuela. In an interview broadcast by the Spanish-language television station Univision on the Sunday before his inauguration, he accused Hugo Chávez of having "impeded progress in the region" and "exporting terrorist activities".

These remarks were unusually hostile and threatening even by the previous administration's standards. They are also untrue and diametrically opposed to the way the rest of the region sees Venezuela. The charge that Venezuela is "exporting terrorism" would not pass the laugh test among almost any government in Latin America.

José Miguel Insulza, the Chilean president of the Organisation of American States, was speaking for almost all the countries in the hemisphere when he told the US Congress last year that "there is no evidence" and that no member country, including the US, had offered "any such proof" that Venezuela supported terrorist groups.

Nor do the other Latin American democracies see Venezuela as an obstacle to progress in the region. On the contrary, President Lula da Silva of Brazil, along with several other presidents in South America, has repeatedly defended Chávez and his role in the region. Just a few days after Obama denounced Venezuela, Lula was in Venezuela's southern state of Zulia, where he emphasised his strategic partnership with Chávez and their common efforts at regional economic integration.

Obama's statement was no accident. Whoever fed him these lines very likely intended to send a message to the Venezuelan electorate before last Sunday's referendum that Venezuela won't have decent relations with the US so long as Chávez is their elected president. (Voters decided to remove term limits for elected officials, paving the way for Chávez to run again in 2013.)

There is definitely at least a faction of the Obama administration that wants to continue the Bush policies. James Steinberg, number two to Hillary Clinton in the state department, took a gratuitous swipe at Bolivia and Venezuela during his confirmation process, saying that the US should provide a "counterweight to governments like those currently in power in Venezuela and Bolivia which pursue policies which do not serve the interests of their people or the region."

Another sign of continuity is that Obama has not yet replaced Bush's top state department official for the western hemisphere, Thomas Shannon.

The US media plays the role of enabler in this situation. Thus the Associated Press ignores the attacks from Washington and portrays Chávez's response as nothing more than an electoral ploy on his part. In fact, Chávez had been uncharacteristically restrained. He did not respond to attacks throughout the long US presidential campaign, even when Hillary Clinton and Joe Biden called him a "dictator" or Obama described him as "despotic" – labels that no serious political scientist anywhere would accept for a democratically elected president of a country where the opposition dominates the media. He wrote it off as the influence of South Florida on US presidential elections.

But there are few if any presidents in the world that would take repeated verbal abuse from another government without responding. Obama's advisers know that no matter what this administration does to Venezuela, the press will portray Chávez as the aggressor. So it's an easy, if cynical, political calculation for them to poison relations from the outset. What they have not yet realised is that by doing so they are alienating the majority of the region.

There is still hope for change in US foreign policy toward Latin America, which has become thoroughly discredited on everything from the war on drugs to the Cuba embargo to trade policy. But as during the Bush years, we will need relentless pressure from the south. Last September the Union of South American Nations strongly backed Bolivia's government against opposition violence and destabilisation. This was very successful in countering Washington's tacit support for the more extremist elements of Bolivia's opposition. It showed the Bush administration that the region was not going to tolerate any attempts to legitimise an extra-legal opposition in Bolivia or to grant it special rights outside of the democratic political process.

Several presidents, including Lula, have called upon Obama to lift the embargo on Cuba, as they congratulated him on his victory. Lula also asked Obama to meet with Chávez. Hopefully these governments will continue to assert – repeatedly, publicly and with one voice – that Washington's problems with Cuba, Bolivia and Venezuela are Washington's problems, and not the result of anything that those governments have done. When the Obama team is convinced that a "divide and conquer" approach to the region will fail just as miserably for this administration as it did for the previous one, then we may see the beginnings of a new policy toward Latin America.
