>other countries rarely get talked about in this same way
They actually do, but the Israeli lobby has grown so powerful that it is now dominating most of the political action in the USA in a way that has become impossible to ignore.
There are actually plenty of conversations to be had about Indian ethnic affinity and lobbying. USINPAC is the Indian lobbying organization which is actually modeled after AIPAC (the notorious Israeli lobbying group which has political control over most of the US congress).
There is a looming argument which hasn't yet entered the public mainstream discourse about Indian foreign influence and Indian ethnic nepotism in the United States, but that is an entirely separate conversation.
Most Indian CEOs are the same caste (Brahmin) and there is a good argument that many of them have been nominated by the boards of their companies and institutional investors with large stakes so that they can navigate India's notorious bureaucracy and deepen ties to the country, which supplies much of the cheap labor for the tech industry. Many of them have direct ties to the Bharatiya Janata Party in India and can use the access to people like Modi to access more Indian labor as well as build more in India. Modi talks openly about exporting human capital and using its diaspora to wield influence in the United States. One can argue that they are taking a queue from Israel here.
