Its in times of crisis that neighbors are the ones that should stand together, simply because geography remains immutable.
It would be naive to think help would be offered and would result in long sustainable improved relations, but IMO just as we've reach this point of hostility incrementally over our shared history, there must be a way out.
Perhaphs, even naively, despite the past examples of such initiatives falling flat, one can hope that we would be able to resolve our problems peacefully. It remains an undeniable fact that to ascend to a global power, India would need her borders to be stable, peacefull and manned by friendly nations.
If England and France can be at each others throats for most of their history and resolve their differences peacefully to emerge as partners, why can't we?
One can hope.
