You don't fight like it's a insurgency, we don't have to occupy the whole country, we have to occupy the strategic area's
Such as capturing rangpur, dinajpur near Siliguri near Siliguri corridor, cox bazar some area's in Chittagong hills
The USA in Vietnam wanted to install puppet govt, same thing in Afghanistan & Iraq, but they failed & fought decade long inseergency guerrilla war, so did we in srilanka, our work was maintaining the law & order for the people who didn't want those, same thing USA did,
We don't have to fight like ipkf nor occupying the whole country or maintaining law & order, gaining terrority is definitely futile, gaining the fertile land is definitely not a loss, we get widen the corridor, a port to link up with north east do you really think the Chinese didn't gain anything from the captured akasi chin & areas in Arunachal
Fight like russkies means how they bombed the city of grozny or the town's near dinper, donbass, which have become a ghost towns, nobody lives there, no civilians population means no space for guerrilla warfare,
