Karachi is out of the sphere of influence where the Strait of Hormuz is concerned which is the center of gravity of the great game being played out in the middle East.
This article is pretty lame. The author is unaware of the fact that Chabahar Port in Iran which India is building is Iran's closest and best access point to the Indian Ocean and
nearest to the Strait of Hormuz choke point.
The plan is to link Chabahar free trade area to Iran's main rail network, which is connected to central Asia and Afghanistan. This would provide more capability for Chabahar for faster and better logistics in the sector compared to Gwadar. Besides financing the Chabahar port, India has also built a 218 kilometer Zaranj-Delaram road in Afghanistan’s Nimroze province which will connect to Chabahar port via Milak. This will open the Indian market to Afghanistan.
Strategically, being only 180 nautical miles from the exit of the Straits of Hormuz,
Gwadar, being built in Baluchistan coast, would enable Pakistan to take control over the world energy jugular and interdiction of Indian tankers.
To counter this, India has built the Chabahar port which is closer to the Strait of Hormuz and thus neutralizes Pakistan's advantage. The energy jugular will now be in Indo-Iranian hands.
