World News is always bound to be dominated by the news of the spoken language. While English is spoken very broadly, the US is the dominant speaker by population. Most "international" news will be written in the native language of the afflicted area. Since people here want English content, you're going up see mostly English speaking areas. Since the US is the largest, it'll be mostly US news.
If you don't like it, start sourcing interesting English content about non-english locations.
