If this "BRI alternative" can't help with Israel's blockade, what good is it?
Most plans made by India are just lip service for public consumption, to delude the citizens that India too has a plan to compete with it's rivals.
Unlike China, India isn't a major trade partner of every country on the globe, nor a major exporter; so what would have been the significance of building such a corridor? There isn't sufficient demand for it's use. It's like Mongolia building a corridor to Canada.
Indians are also quite unreliable when it comes to international projects. When China was developing the Gwadar Port in Pakistan, India made deals with Iran to develop the nearby Iranian Chabahar Port which would then be connected by rail to Afghanistan and Central Asia. But when US slapped sanctions on Iran, India was among the first to follow US. Iran then expelled India from any such projects and decided to join China's BRI and even connect to Gwadar.
India makes unviable, delusional plans. Nothing else. It seems that they don't actually have any long-term strategy and just act spontaneously on current trends with short-term thinking.
