Why more troops??
India being squeezed from all sides. Keep them busy at all fronts.
During WOT ( 2003-2016) , India brought war inside Pakistani territory. India was also able to push a narrative such as Pakistan being epicentre of terrorism. However things have changed now over in last 5 years.
After elimination of TTP in Afghanistan, along with killings of several anti Pakistan NDS and BLA members over last 6 months, Pakistan has finally started to focus on India. Given the current domestic pressure Modi government finds itself in, its high time that all Indian proxies are wiped out.
The only tactic that works against India is , pressure tactics which involves taking war back to India. Since Aug 2018 when Imran Khan became PM, India's soft image has been eroded by a narrative pushed by Khan's government and diplomats including foreign missions in several countries. Biggest proof is Imran Khan's UN speech or just check Imran Khan's twitter account. This erosion in soft image has been reinforced by Modi government's stupidities and diplomatic errors. When people in west see images of Muslims being lynched and butchered or Hindus destroying mosques they certainly realise that India is not all glamour and diversity. The hinduvata ideology floated by BJP, didn't help either. The deportation of several Indians from Gulf state is an example, where Indians are now seen with suspicion.
The ground realities are changing rapidly, India has to respond/adapt quickly. Panic is evident within military and diplomatic circles of India. Modi is increasingly becoming a security risk for Indian state, but the establishment doesn't have enough spine to take him down.
