In a pot, cook the bacon over medium-high heat until done. Drain half of the bacon grease, keeping half in the pot. Add the butter and the onions and cook until they are soft and translucent, 5-7 minutes. Add the garlic and cook for another minute. Add the white wine and bring to a boil. Boil for a minute or two until mostly evaporated. Reduce the heat and stir in the tomato paste and the flour until the flour is incorporated. Add the potatoes, capers, seasonings, chicken broth and clam juice. Bring to a boil, reduce the heat, cover and simmer for 20 minutes.
Add the cream cheese and stir until melted. Stir in the heavy cream and the smoked salmon and simmer for another minute or two just until heated through (avoid simmering too long or the salmon will become mushy). Discard the bay leaf. Add salt and pepper to taste. Serve immediately with some good crusty bread and/or saltine crackers.
