First thing, I don't think India will get entry into UNSC.
Second India's strategic roadmap, doesn't really depend on it being in the UNSC seat.
Third Pakistan is doing it's due diligence and has legitimate reasons to voice it's concerns, although it's opposition has little bearing on a non-issue.
Support of India's by US, France, UK and Russia is pure lip service, when it comes down to it, both US and China will be against it, with france siding with US.
Indians have to remember, you have to stand on your own diplomacy, Independent India First policy as always. There is no need to meddle or arbitrate in International conflicts unless our own interests are at stake. India First, Always.
