And it has not asked Pakistan .. and that's a perfectly good reason for that, which is above the intellectual levels of Godi Media who happen to dumb down all Indians every day.
Indians can keep screaming about it 20 times a day like they have been since last 1 month and that won't amount to anything. We know who that pact is for (again, not for Iran) and when the time comes, Pakistan will be ready to act on it. Pakistan just reused to vote in favour of a GCC resolution in UNSC today (that was bought by GCC, against Iran) so there is a lot more to this issue, than you know.
Now please relax.
