Because situation is fluid.
What pak & CCP are doing is War on our perception . We are their target.
When we think about it, pak with their few hundred jihadis at a time can achieve nothing in Kashmir, similarly few hundred PLA soldiers in Ladakh can do nothing tactical.
their actions have more to do about messaging & posturing rather than anything concrete.
If Modi says and commits to something, it becomes easier for them to focus and try to undermine the very thing he would have made the statement about. in a few scenarios, not saying anything at the top gives us more options.
THIS
In chinas case they have a strategic view present as a matter of policy,i.e it is systemic rather than provided by any leader.it is enforced by their laws,government,historical events,culture,etc.A chinese individual leader may have a short term scheme to achieve something but it will not affect the longterm strategy of china.
In our case we are a nation of more few good men rather than good systems.(Not saying that it in black and white terms,but compared to china we dont have an ecosystem promoting and protecting our frontline troops whether it be info warriors,soldiers, psy warriors and motivators,etc)We expect the individual leader to formulate a strategy when he comes to office itself not knowing that war is to be ideally conducted in a totalitarian manner where every aspect of a nation contributes and knows its role.
This is not to say we dont have any systems in place and of all our systems in place all are found lacking.
Like everything its a mixed bag where few are really rotten and actually a burden to be cut out(ofb,etc).
Most are pretty meh all will adequately do what they are meant to do(hal,etc)
while a few again are our premier orgs which bring us a lot of return in investment(drdo,isro,etc)
This is in all fields of india not just war.
My point in all this is that we should move to a purely systemic country where there is already a strtegic outlook on things(especially out current topic of war and territory expansion) from the whole body of the nation from its people minds and thoughts,the messages given by all institutions,news outlet messaging,etc rather than focus on a semi individual ,semi systemic country we have now.In some areas we are like this but i feel in many areas we either semi or completely dependent on the individuals manning the post whether it is an ias officer or a miltiary commandeer or a minister.If that guy by some luck has a good thought we are saved otherwise .....
This is the thing i always felt when i see china and india.we are focused a little too much on individual great men to carry our team when we should have the whole team focusing and doing their role to the utmost potential they can be performed with those great men being a bonus or anchor.
dont be like a cricket team where if one player does not bat then the whole team loses.
