You have suggested plenty of policies, can't cherry pick just one thread. Pretty much every member has. This is all part of the discussion.
Was not a priority issue, there were 100's of way more important things to fix (and much better lower hanging fruit at federal level too). But now that those have been fixed, or are in the process of doing so etc this gets bumped up the list with time and the pressure/reminder from this minister is welcome....you seem to not understand how delegation/prioritisation works in the Indian political set up....not everything is done at federal level all the time and all together.
The state level at Assam is where BJP is working hard on this issue (and that broadens into N.E)...and BJP needed to win the state first. Similar to much other economic reforms and policy, state control is needed by BJP. We need that done comprehensively first so something is actually realised when federal bureaucracy + leadership invests political capital into it....which can certainly be around the corner (given BD election cycle), lets see.
Over time yes we need a much better federal security apparatus with eye on illegal immigration like ICE in the US. But that will take time to build up in India institutionally (UIDAI has just commenced and needs to build up its credibilty), right now its important to experiment with what works best in setting up the precedent for later.
She is playing right into polarisation politics, and thats going to be her downfall...it happened in other states over time too. I credit her with bringing down the commies, but she is just a transition stage till BJP sweeps there too....because time is running out for her to deliver to the W. Bengali electorate past the identity politics (which are diminishing in importance at a furious rate these days as we saw in UP).
She is quite friendly to Bangladeshi illegals too (given they vote overwhelmingly for her), so when she is gone and there is a state coordination in dealing with that issue it will probably have a precedent from Assam on how to do it best.
We will do something half-way between most likely for now. First we need 2018 to play out a bit and how much we can extract (political capital) from what we invested into SHW. Documentation does not figure into this because no BD illegal keeps documentation (its the first thing they destroy) on hand, rather they acquire Indian one to try claw some status there. Hence why Assam set up specific tribunals. BD recognition of it does not really figure into it, you are not a cooperating entity on the issue, hence we will try smooth it through SHW first, if not, so be it....BDR got replaced quite bloodily by BGB for a similar reason....we will conduct a few more of those to create and sustain bullet-enforced one way deportation routes in the border. BGB lets the BSF operate with pretty much total impunity as it is, it wont be a big stretch anyway...just worth letting SHW agree/allow (even tacitly) first before the stick has to come out.
