Lets be honest, America do not have audacity to launch any kinetic action against China, let alone its sidekick India. For all the practical purpose, this BECA agreement will be actually used against Pakistan in any future military conflict.BECA agreement negotiations have been going on a couple of years so it's no surprise as to what the deal is. The Indian Armed Forces were the main opponents to the deal but both the government and armed forces found common ground and compromised over the main issue they have right now which is the Chinese knocking on their doorstep. Though their main target is China, no doubt they will not hesitate to perhaps use it against Pakistan or other threats that they perceive. Legend summed it up perfectly that we should look to try and leverage our own deals with the US, not follow this mentality of 'you are with us or without us' the same mentality which plagued the US war on terror specifically in Afghanistan.
If a hypothetical Large scale conflict (Not only in Kashmir area but the whole border) occurred between both India and Pakistan with India being the instigator in such scenario, not only would India jeopardize a friendly relationship with the US but also face possible sanctions from them. It would also make the US very nervous as to what India's true intentions are the region aside from containing China and upset the balance. So targeting US assets while also at war with an opponent like India is surely to be the nail to our coffin rather than a benefit to us.

There has to be a complete understanding of the ground realities that China itself will never see a military action against it as the consequences for instigator nation/s are just too horrific to bear. Instead, the Chinese outreach and influence, both regional and global will be targeted. Hence you see a very strange pattern of instability appearing in central Asia. and ofcourse Pakistan and its CPEC sticking out as a sour thumb. Its the Chinese "periphery" (which includes Pakistan) have been/will bear the brunt of the hybrid and direct military wars and conflicts. Understand BECA under this pretext and understand how it will effect Pakistan national security.
If we understanding our own national security from "what if" scenario of India jeopardising its relationship with America and possible sanctions, how does it even qualify to be even considered when we have already been targeted and our soil is bombed by India using American space base eyes and ears? Do you really want to leave your national security to such flawed assumptions? Even if America sanction India or cut off its ties with India, how does it benefit Pakistan after it has been already on the receiving end? No sorry, national security policies are not made on such flimsy grounds.
America and India, both understand their non existence military options against China and let there be no doubt that their military agreement is all about targeting Pakistan. For American, to cut off Chinese access via CPEC, and India, well we know the reasons.
We need to make America aware, in no uncertain terms, that if America own state assets are used by India to target Pakistan , under this BECA agreement, then we are bound to respond militarily the way we see fit.
