Post the downing of the Indian Air Force (IAF) MIG-21 by Pakistan over its territory and the capture and subsequent return of the pilot, the narrative which was strongly in favour of Narendra Modi and the ruling Bharatiya Janata Party (BJP) rapidly spiralled downwards. Whether the Pakistan Air Force (PAF) entered Indian air space to deliberately attack Indian targets and was driven back, or it was a lure to ambush the IAF aircraft over Pakistani airspace, is not yet clear, but the stark acknowledgement that the IAF MIG-21 had been downed and the pilot captured, and a video of his capture and interrogation broadcasted on social media, were setbacks to the Indian government and its military. Although the Indian government claimed that a PAF F-16 was brought down (although some Indian defense commentators are stating that this is evidence of the downed PAF F-16), Pakistan is denying any loss of its aircraft.
If the market was banking on a decisive Modi victory in the 2019 national elections in the immediate aftermath of the IAF strike on Bagalkot that has been dissipated with the capture and return of the IAF pilot. Unless another such event arises (or is generated), the outcome of the national elections in India will be determined by political alliances and the socio-economic conditions of the electorate; national security concerns may play a secondary role
