Bhai, it still matters. As an example, why Trump pummels and disgraces Modi so frequently? Because Pakistan wisely asked USA, KSA, etc. in May 2025 that if Pakistan accepts the request for ceasefire (under such and such Pakistani) conditions, who can give the guarantee that Modi will abide by that agreement? Trump administration was readily willing to offer that guarantee and so Pakistan agreed. Modi later disgracefully backed out from his commitments given to Trump. And so, you see what he is doing with Modi and India.
Apart from verbally slapping Modi every other day, the US government has put significant tariffs/restrictions on Indian exports to the US and removed many waivers especially given to India (Russian oil and Chabahar, etc.) Modi cannot go to any place/platform where American president is present. The same is true for Jaishankar too. He ventured out only to NY for UNGA session but could only meet a few African counterparts or lower ranked officials. Modi and Jaishankar are effectively hiding and living a life of a rat in his hole.
That's the benefit of involving international community.
