yes you are right thats what plan right now,
before let say not arguing its just discussion about a secnario or strategy which india is not pursuing,
if india is employing millions of sri lankans,providing them jobs and income and many of them marrying in india and have relatives in india then wouldnt it be better if sri lanka gets annexed to india,
usa and canada are different they both are same size,
annexing not always required,but look at benefits of it,
sri lanka is an island not exactly tiny one we can make it navy base,beach tourism base indias own hawai
,natural resources,
this cannot possible without annexing,
because if not annexed then other way is lobbying their each and every government that comes to power which may not be
that friendly to india so this not gonna be always smooth and others are also in line to do that,
this is what china is doing currently that right now,
when it comes to nepal ,bhutan no need to annex them as they are geographically on the indian side of himalaya and on not china side so they very much depended on india and geographically connected to india,
and also indians and nepalis are free to live or work on any side of border.
