Nepal's Parliament including 3 disputed areas in a new map & other recent developments have marked a low point in relations between the two countries.
It takes two hands to clap and both the Nepalese and Indian sides have to be blamed for letting relations deteriorate.
On the contrary the Indian side are using an agreement with China in May 2015 on trade through Lipu Lekh to buttress its position.
Nepalese Monarchy though aware of the dispute never brought it to a boil to ensure smooth ties.
This changed as political parties came in, politicisation of foreign policy took place & Nepal asserted itself.
Insult to injury was added when despite requests for talks from Nepal no heed was paid
Final blow from Nepal's perspective came with road being inaugurated by India in May 2020
This perhaps inflamed popular public opinion more than any cartographic aggression.
Remember now that K.P Oli won an election using the 2015 Indian blockade and nationalism as a major election plank.
What followed were undiplomatic language of 'Indian virus being more lethal than Chinese and Italian'.
It was domestic politics over foreign policy.
The timing was also bad as India is embroiled in a border standoff with China.
This time it went 'public' on the Indian side too making this a different spat.
However, all bets are off if both or any side continues making it a central issue.
This was visible in the literally zero help from China during the 2015 blockade.
Geography is a reality that cannot be wished away here.
India is the giant economic and security power of the region.
Nepal is a medium sized but important himalayan state in the region.
Deal with the realities.
