Is nationalism PM Modi's brahmastra in 2019 elections?

Prime Minister Narendra Modi today launched the BJP's campaign from Uttar Pradesh with a blistering attack on the Opposition while keeping the focus on a strong government, saying his administration had shown the courage to conduct a surgical strike in all spheres -- land, sky and space.

The contest is between a "a decisive government and an indecisive past", Modi said at a rally in this western Uttar Pradesh town a day after announcing that India had demonstrated anti-satellite missile capability by shooting down a live satellite.
