"Somewhere along the line whether it's Maduro for awhile or Henrique Capriles [who lost to Chavez in the October presidential election] later, reality must set in,'' said Anthony Bryan, a senior associate at the Center for Strategic and International Studies in Washington.
"Venezuela is currently giving away one-third of its oil production at below market prices: this includes loans-for-oil deals with China, and heavy subsidies in the domestic market," he said.
With soaring inflation, a recent devaluation, high import bills, over-dependence on oil and shortages of everything from meat to toilet paper, the Venezuelan economy is in a downward spiral and the next president may be forced to concentrate more on domestic issues.
But for many Latin Americans, whether they agreed with the Venezuelan model or not, Chavez's legacy will be as a bulwark against U.S. economic and political dominance in the region.
"He was the great leader of the left in Latin America and advocated for a Latin American -- and Caribbean -- way of doing things as opposed to a U.S. way of doing things," said Erick Langer, director of the Center for Latin Studies at Georgetown University.
In addition to being the guiding force behind ALBA, Venezuela was a founding member of the Union of South American Nations, or UNASUR. Chavez also hosted the meeting that forged the Community of Latin American and Caribbean States, an organization that excluded the United States and Canada. Chavez hoped it would one day replace the Organization of American States.
But the apex of such activism and anti-U.S. campaigning came during the second term of President George W. Bush, said Kurt Weyland, a government professor at the University of Texas at Austin who has researched populism in Latin America.
Chavez's anti-U.S. rhetoric reached a crescendo during a Sept. 20, 2006 address to the United Nations General Assembly. Speaking the day after Bush had addressed the assembly, Chavez said, "The devil came here yesterday, and it still smells of sulfur..."
U.S. officials talked Wednesday of a desire to have an improved relationship with Venezuela.
In the past 14 years, the Venezuelan government "really did revolve around one man. So while I hesitate to say that a change in an individual or the passing of an individual completely changes the relationship...he played an outsized role in that government, and therefore his absence can have an outsized implication, if you will," a senior State Department official said.
While Chavez's death represents a "terrible loss'' for sectors of the Bolivarian left, said Arnson, the notion that he was leading a strong movement throughout Latin America "is several years out of date.''
"Since then not only has the U.S. administration changed but so has the world,'' said Weyland. He predicts a lowering of tensions in the region.
Analysts said there doesn't appear to be a clear ideological heir apparent to Chavez and his movement in Latin America. And that may cause the left-leaning coalition forged by Chavez to begin to unravel, said Langer.
But this week Chavez's closest ideological allies reacted with an outpouring of grief and tributes.
Cuba declared two days of national mourning and ordered flags to be flown at half-staff. There were three days of mourning mandated in Argentina and Haiti, and Dominica also declared a state of mourning.
"Chavez will continue to be an inspiration for all peoples who fight for their liberation," said Bolivian President Evo Morales, one of Chavez's closest allies, in a televised speech.
And in Nicaragua, Rosario Murillo, wife of Ortega and his spokesperson, said simply, "Chavez is one of the dead who never dies.''
