Way too early and reactionary to claim that. The truth is, a party that is ideologically bound to function by itself, and at best, with a couple other ideologically aligned parties; needs to have both an LS majority, as the BJP already does, and more importantly, an RS majority, which they haven't acquired yet.
This becomes even more true when you've got people like Modi and Shah who don't play too well with others and who have hugely ambitious goals/objectives that essentially amount to flipping a country around 180 degrees overnight after 70 years of plodding along in the same direction.
So wait until they retain their LS majority in 2019 (hopefully while having to rely on as few allies as possible), and until they manage to capture the RS majority. After that, they basically won't need cooperation from a lot of these other parties/people, and will have their hands untied to go after a lot more corruption and reforms/campaign promises that they didn't have the freedom to pursue. At that point, they will also be able to point to the first term and say clearly, that they tried to cooperate with and take the Opposition parties into confidence, but those parties chose not to play ball and preferred to engage in five years of filibustering instead. The logic there is similar to how Modi attempted a reset with the Pakistanis, we all knew it was bound to fail, but for the sake of optics/building justification for his later stance, he still had to try.
