not to be read too much into it, it is unfathomable that US on one hand will offer cluster munitions, nuke deal, bmds, mmrca, jet engines, space co-op, lpd, aircraft carriers and on the other will hold up 2 turbine engines..
Imo either indian babus messed up, from what i know americans are pretty rigid when it comes to documents and forms or some new young US official of obama administration wanted to prove a point whatever that is (and i hope it is not we will shoot ourselves in the foot that is so unamerican).
