Definitely. But not more than 10-12 years at most since by that time India will more or less be where China today is.
In fact, I believe it will be a blessing in disguise if UNSC reform is delayed. It will give us enough time to grow economically/militarily and hence make our case for a seat with veto much stronger.
Completely agree with you there. We need to focus firstly on our internal issue. Try and reduce hunger, poverty and arms struggle with our borders. Become internally stronger before putting forth our Security council case.
