honestly i dont see india imposing a blockade on nepal as the situation now is totally different. india is emerging superpower and big brother of the south asia imazine how it would look in international circle with india imposing blockade on a land locked country so that the people will bring back democracy whic would be practiced by puppet politicians of the south block of course u can expect alot of diplomatic pressure on govt but that doesnt mean king has to give up rite away afterall mahendra survived for so long with such a strong support from china
