BBC finds Russian guards, Iranian trucks and rusting railway on Trump's Caucasus peace route

The BBC reports on Trump's proposed Caucasus peace route, which aims to redevelop a Soviet railway in southern Armenia into a symbol of peace. The plan involves building a 43km route linking Azerbaijan to Nakhchivan, overseen by US companies under a 99-year deal, which faces political challenges. Russian guards patrol the Armenia-Iran border, while Iranian trucks and businesses are involved in the project, amidst concerns from Iran about US involvement. This initiative could reshape the region's geopolitics, amidst historical conflicts and hopes for new investments in long-abandoned areas.
