The Indos bought a few billion dollar subs off the Russians a while back and probably have plans to buy some Migs or Sukhois in the future.
I'm not a military buff so I really don't know the good/bad/ugly about the F35, but my preference would've been to buy updated versions of F15's or F18's, my guess, more planes for your buck. Or look at some from the Russians. Nothing wrong with diversity

What attack helicopters did we end up getting for up north? I remember the Apache was being looked at but they bought something else.
