Heat olive oil in a large stockpot over medium heat. Add onion; cook and stir until soft, about 5 minutes. Add garlic; cook and stir until fragrant but not brown, about 2 minutes. Stir in tomatoes, wine, water, tomato paste, basil, sugar, pepper flakes, oregano, salt, and black pepper. Cover, bring to a simmer, and cook, stirring occasionally, for 45 minutes.
