 ## Key Features

+### Localization & Regional Support
+
+- **Multilingual UI** — Fully localized interface supporting **English, French, Spanish, German, Italian, Portuguese, Dutch, Swedish, Russian, Arabic, Chinese, and Japanese**.
+- **RTL Support** — Native right-to-left layout support for Arabic (`ar`) and Hebrew.
+- **Localized News Feeds** — Region-specific RSS selection based on language preference (e.g., viewing the app in French loads Le Monde, Jeune Afrique, and France24).
+- **AI Translation** — Integrated LLM translation for news headlines and summaries, enabling cross-language intelligence gathering.
+- **Regional Intelligence** — Dedicated monitoring panels for Africa, Latin America, Middle East, and Asia with local sources.
+
 ### Interactive 3D Globe

 - **WebGL-accelerated rendering** — deck.gl + MapLibre GL JS for smooth 60fps performance with thousands of concurrent markers. Switchable between **3D globe** (with pitch/rotation) and **flat map** mode via `VITE_MAP_INTERACTION_MODE`

+# News Translation Analysis
+
+## Current Architecture
+The application fetches news via `src/services/rss.ts`.
+- **Mechanism**: Direct HTTP requests (via proxy) to RSS/Atom XML feeds.
+- **Processing**: `DOMParser` parses XML client-side.
+- **Storage**: Items are stored in-memory in `App.ts` (`allNews`, `newsByCategory`).
+
+## The Challenge
+Legacy RSS feeds are static XML files in their original language. There is no built-in "negotiation" for language. To display French news, we must either:
+1.  Fetch French feeds.
+2.  Translate English feeds on the fly.
+
+## Proposed Solutions
+
+### Option 1: Localized Feed Discovery (Recommended for "Major" Support)
+Instead of forcing translation, we switch the *source* based on the selected language.
+- **Implementation**:
+  - In `src/config/feeds.ts`, change the simple URL string to an object: `url: { en: '...', fr: '...' }` or separate constant lists `FEEDS_EN`, `FEEDS_FR`.
+  - **Pros**: Zero latency, native content quality, no API costs.
+  - **Cons**: Hard to find equivalent feeds for niche topics (e.g., specific mil-tech blogs) in all languages.
+  - **Strategy**: Creating a curated list of international feeds for major categories (World, Politics, Finance) is the most robust & scalable approach.
+
+### Option 2: On-Demand Client-Side Translation
+Add a "Translate" button to each news card.
+- **Implementation**:
+  - Click triggers a call to a translation API (Google/DeepL/LLM).
+  - Store result in a local cache (Map).
+- **Pros**: Low cost (only used when needed), preserves original context.
+- **Cons**: User friction (click to read).
+
+### Option 3: Automatic Auto-Translation (Not Recommended)
+Translating 500+ headlines on every load.
+- **Cons**:
+  - **Cost**: Prohibitive for free/low-cost APIs.
+  - **Latency**: Massive slowdown on startup.
+  - **Quality**: Short headlines often translate poorly without context.
+
+## Recommendation
+**Hybrid Approach**:
+1.  **Primary**: Source localized feeds where possible (e.g., Le Monde for FR, Spiegel for DE). This requires a community effort to curate `feeds.json` for each locale.
+2.  **Fallback**: Keep English feeds for niche tech/intel sources where no alternative exists.
+3.  **Feature**: Add a "Summarize & Translate" button using the existing LLM worker. The prompt to the LLM (currently used for summaries) can be adjusted to "Summarize this in [Current Language]".
+
+## Next Steps
+1.  Audit `src/config/feeds.ts` to structure it for multi-language support.
+2.  Update `rss.ts` to select the correct URL based on `i18n.language`.
