Having USA in BoB will not make any difference to China. Just look at the map. When you are worried about getting surrounded by China actually you will be surrounded by USA.
I dont support permanent base in BoB. We need to take care of our own security. USA might give us 200, F-15, 10 Submarines and some other tools so that we do the job on their behalf in BoB.
Yes, you are right. No doubt, many US equipments will be forthcoming to Bangladesh. A treaty to facilitate US military will not be a dry one without weapons. BD military top brass will not allow the govt to sign such a treaty without any material gain for the country.
In lieu of its good overtures towards USA, India remains basically in the Russian block. With a military facility in BD, USA implies a China triangulation only to appease India. US-BD military alliance may well mean a triangulation of India. Other points of triangulation are Pakistan, Diego Garcia and SL. India has now been completely caged within itself.
BD really needs a very strong navy for the protection of not only the BoB, but also its mainland. One weak point is the narrow strip of land between Tripura and the sea. At a time of hostility India may threat us with a double punch, a naval attack from sea and a land attack from Tripura that will separate the entire CTG zone from the mainland.
Perhaps USA understands this and has already installed radar stations somewhere at Kuakata and Cox's Bazaar to observe Indian naval movement. But, BN needs a strong navy as a deterrent.
