Juliana Fombona said she felt a surge of hope when she learned that the U.S. military captured Venezuelan President Nicolás Maduro from Caracas on Saturday. But that optimism was fleeting as she began to ponder what the future might hold.The same political forces behind Mr. Maduro are still entrenched in her home country despite his removal, said Ms. Fombona, an architect who has lived in Halifax for 23 years. And it’s still unclear who will run Venezuela, whether democracy will be restored and when the humanitarian crisis may improve.
