India has invested 2 billion in co-development of the Barak 8, it is jointly owned IP and any unauthorized use of it by Israel is a violation of the JV. Just as if China sold FC-1 with no Pakistani involvement.
Which is kind of jacked considering it was a 50/50 JV. If Israel wants to screw India there is plenty of room on the blacklist for their companies to go on.
India would never approve of that deal. IAI has cut out India as a supplier and has no veto on where it is sold to. This joint project is about as one sided as a one way street.
