To summarize, in terms of social indicators our country would maintain status quo. There would be no significant improvement in healthcare and education, although there might be a minor reduction in poverty as a result of economic growth. On the other hand, India will not become a Fascist country, or a Hindu state, and the state itself will not get directly involved in persecuting members of any vulnerable community. Instead, here are some of the things that probably will take place in India, as a result of these elections.
Markets would open up more in India, foreign investment in various sectors would be encouraged, more SEZs would be created, and tax cuts and benefits would be gifted to big corporations. Forced land acquisition might become common. An improvement in ease of doing business would presumably boost the economic growth and create more jobs for the middle class. It would also fill the already deep pockets of our Ambanis and Adanis. The government would be made smaller, in terms of number and size of ministries and possibly in terms of overall investment in the public sector. Some of the existing welfare projects aimed at the poorest members of the society might be scrapped, and new ones would not be introduced. This would also reduce government level corruption and wastage of taxpayers' money to some extent. Some of the less powerful politicians of the previous government would be prosecuted on corruption charges.
India's foreign policy would become more assertive, and in some cases mildly aggressive. This would be a shift from the soft state that India has traditionally been perceived as, especially throughout the last decade or so. There will be no war, but there might be increased skirmishes at the border and escalation of tension with Pakistan and China. On the other hand, stronger relations would be sought with countries in South East Asia, Japan, the US and Israel. Relationships with Iran may deteriorate. Strong anti-terrorism bills would be passed, targeting both Jihadi elements and Maoist insurgents.
Public funds would be spent on propagating Hindu nationalist ideology. This would be implemented through subtle changes in school curriculum by depicting Hindu glory; through promotion of Sanskrit, Indian astrology and Ayurveda, and through more ostentatious displays of Hinduism in government activities. Funds would be earmarked for the protection of cattle. These influences, would mainly entail a softer version of Hindutva. The effects of a stronger version of the same would be felt as well, though not directly through government initiatives.
Groups that do not enjoy economic influence or political clout, or those who represent ideas that do not conform entirely to the doctrines of Hindu nationalism would be targeted and persecuted by fringe groups that adhere to a more extreme version of Hindutva. Target groups would range from religious minorities, homosexuals and Kashmiris, to the politically liberal. Vigilant groups and self-appointed moral police would feel encouraged, and incidents of rogues beating up people celebrating Valentine's day or women drinking alcohol would increase. Freedom of speech and freedom of press would both decline to some extent and critiques of the government or Hinduism would be attacked more severely and frequently; again not so much by the government itself but by fringe groups who would now enjoy some level of state protection. These spurious attacks, however, would still generate further criticism from sections of the population, and at some point, the government would be forced to draw a line and put a check. Moreover, the BJP would be keen to not antagonize Muslims, knowing that the landslide victory would not have been possible without a considerable number of Muslims voting for them this time.
All of these, needless to say, are mere speculations, and the truth will only become evident in five years' time. It can be guaranteed, however, that overall, India will continue to be the slow and sluggish elephant that it has been as far as change is concerned, since time immemorial; and neither would its problems go away, nor would its rich and diverse social fabric be destroyed. Both India's problems, and the "Idea of India" are too deep-rooted to be obliterated by a single election.
