Game changer port of Gwadar Pakistan

China is building a port in Gwadar Pakistan , if you look at the map you can see how close this port is to the Straits of Hormuz and strategic water ways, that carry something like 40% or more of the worlds energy supplies.
**
Imagine Chinese submarines cruising these waters 7-15 years from now, heck China could even turn the tables on the US, one were the US energy lines could be cut to the US and her allies.
**
The implications of this port are huge, China could directly get her energy needs from Gwdar, and build pipelines and rail links to this point, shortening her supply routes and creating energy safety from the US Navy.
**
What ever happens in this port will have major strategic implications.
