Re: Goa - why?
What was legal about it? The only reason why India did not face a UN resolution against its invasion of Goa was because the Soviet Union vetoed it!
Portugal’s eventual acceptance of the Goa situation 13 years after India’s invasion of Portuguese land was an acknowledgement of the fact that Protugal lacked the resouces to take back Goa militarily and had a choice between accepting the situation or having no relations with India at all in perpetuity.
