Lmao. They were always and never desperate at the same time, if you know what I mean. This was predicted by many during the late 2010's and after 370 was scrapped. Pakistan will change tactics after 370 was always guaranteed. Many veterans had laid out the exact scenario that is playing out now. Small teams, mainly involving Paki terrorists ambushing and scoring small attacks against either the local Jammu population or isolated units of CAPF/ POLICE/ ARMY. The paki strategy was to keep the fire of insurgency burning in local Muslims even if it meant drop in number of attacks. Look how they good and successful they have got in executing this. So yeah, they are desperate but desperate to kill isolated squads or ex servicemen and not attacking major establishments.
And they aren't desperate because after 370 and Surgical strikes and Balakot the onus is on Modi. Every ambush puts pressure on Modi, not on Pak. So they just need to maintain these ambushes once or twice every 2 months and the ball is in Modi's court to reply.
They just skyrocketed that pressure after attacking Jammu. Jammu attacks are returning the favour for scrapping 370. Believe me, Jammu is just a start. Expect attacks in Punjab or Himachal as well. 2 guys were spotted in Gurdaspur few days back. Then a tunnel.waa spotted near the International border. Trust me brother, they aren't desperate to win. We are desperate for peace.
