The worry that Nepalese will loose trust and friendship out of concern.
Indians I think most of them welcome Nepal as 30 th state, the article is just a signal of Intent from Indian side ....... regarding Nepal joining India it is left to them to decide .... if they agree just like Sikkim then the concerns you have expressed will not be a problem.
Regarding China ..... with the rise of China the policies and geo politics will change to counter the influence.
We have to be logical instead of being emotional .
How do you think majority of Nepalese will react to any such proposition ?
what has India has to offer to Nepal to lose its sovereignty ?
India is not US ....India is still a third world country with 1/4th of world poor and hungry people ...
India has long way to go and develop to provide honorable and comparable standard of living to its masses ...
Till India has achieved something tangible for itself ..expecting any other country to join India is laughable ....
Most Indians don't care about Nepal or anything else for that matter .
most Indians only worry about their daily bread ....
Let it be loudly clear ...Nepal is not Sikkim ....
As long as there is no such proposal from Nepal ...we have no reason to waste our time of ifs and buts ...and vitiate the nice unique friendly relations that we share with Nepal ....
