Most of the Indian bureaucracy dont collaborate or gel well. They work in silos , more or less bcos they are remnant of british colonial administration and quite often they are a separate power block unto themselves. Some depts in Indian administration certainly have those arrogant elite status , MEA is one of them.Jai shanker was only brought in to keep hold in MEA because MEA doesn't go well with the intelligence and military apparatus of India. But this strategy failed. Because S Jaishanker started to have dialogue with the Chinese and here you are with lost territories.
Govt should reform the bureaucracy and bring in the changes. But they dont care to do it bcos it serves their interest in keeping slaves who just listen to them rather than ppl who might hurt their ego's & power. Jaishankar is the FM bcos our boys dont have any interest in running the foreign policy as it does not fetch any votes. End result is that we have a place holder which simply puts up a show of existence. If you expect too much from it, its your problem.
