And I dont know why you calling US nuclear missiles and systems as duds. SUCH BLOODY TESTS that India conducts, USA conducts daily. Do you know USA regularly carries out testing of it's deadly ICBM Trident and the total has now touched 240 tests. IT WORKS. Dont think by doing a test here and there India can attack USA and get away with it. USA will strike back and your stupid bollywood 'superstars' will be hiting in their cozy homes.
Even Indian defence ministery and Indian army dont imagine in their wildest dreams of attacking USA.
