1.no. indian ocean is the most strategic. watch the video
2. India's geographical advantage in the IOR (indian ocean region) provides it a undeniable advantage, such that not only its navy, even the airforce has bases deep in the islands of indian ocean. i dont expect you to understand this because you seem to be an amateur in this area.
History comes to mind when Indian and and US navy faced off once in 1971 war, each posturing with its aircraft carrier group
My point is, since the europeans invaded india by the sea, india has built a strong navy since independence so that
even the US navy today cannot repeat history.PS: i hope by 'our' you meant US, if u meant chinese navy in the IOR, then its just sad
