Pakistan is China's client state ? Is our relationship with Armenia same ? Supporting a side by providing military equipment is direct involvement, just like Americans did in Syria and Yemen. Does not necessarily mean having boots on the ground.
First of all make some sense before raising a point.
China supports porks and we have been mum about it for decades.
They have been providing arms , money to Naxals and other groups throughout India.
Direct Involvement is when our own troops or fighter jets meddle in the affair.
Israel provided equipment even their advisors technical staff came in during Kargil but that wasn't a direct involvement of Israel.
Even Russia is supplying arms etc but not involved directly yet.
And let's say we wish to project our power there and teach Azer and Turks a lesson to keep mum abt India's internal affair
Those who have issue can keep their ass over an icepack.
