We should invest in Nirbhay and GOI should not buy any of the Tomahawk for the reasons that 1. It is banned as per international law. 2. It is strategic missile, therefore we cannot trust uncle sam. 3. For last many years our arm forces perticularly the IA has chosen Foreign mall over the domestic product.....(ofcourse the role of the agents and retire officers are to be blaim along with hefty percentages in these deals) 4. US has source code for these missile therefore we cannot use it against Uncle. 5. Their domestic laws can stop the delivery of spear parts and inspection clause in deals with US. 6.US wants to dump this tech to India, since India already has state of the art Brahmos, which even US dont have. 7.Last but not the least by selling Tomahawk they will kill any R&D in the domestic cruise missile field therefore we cannot make any long range cruise missile and will be dependant on US.
