India can use Lebanese port for trade with Europe if east of Mediterranean is the case.
Islamic world will not tolerate Israeli existence for sure, it will always be a problematic route for India.
Which ever route Indian think tanks may consider, they should think about this very important fact too.
Arabs esp Emiratis tried to develop a sea route to trade with Israelis and it ended up with Israeli ships being bombed and burnt before reaching UAE ports.
Instead of looking for trouble under US leadership, other ports exists already.
The US proposed route is ridiculous and the reason why Arab monarchs didn't point to it is that they have no choice when it comes to US orders. But India as an economic giant, has to decide freely.
India-Pakistan-Iran-Syria-Iraq-Lebanon
or
India-Pakistan-Iran-Turkey-Europe
The second option doesn't force Indians to jump from ships onto trains which doubles the cost of trade.
Problem would be getting the westernized Pakistani decision makers (army) in line with this axis. Which is good for peace and stability of this region.
Turkey needs not worry. This route is suboptimal compared to the existing shipping route through the Suez.
I believe Indians know that too, they are just playing along with the bonesaw guy. That guy really wants to do something for his country's future but comes up with stupid ideas. This is another stupid idea along the lines of The Line city.
That's an American idea. It ends in Israeli port.
