At this point, it appears Washington is going to give India a pass on having to sign the
non-proliferation treaty. This is mostly because Pakistan won't sign it either.
Since we value India as a democracy in it's region, we will probably not hold sanctions against them.
If we refuse to sanction Pakistan and India, who have performed nuclear tests (Israel has not and is not officially a nuclear power), North Korea and Iran can make the valid claim that they are being treated differently from 'friends' of the US.
