Indians are argumentative and sales driven like Israelis, but you still need to operate the same way you did in China in the 2000s, with local contacts and recognize that you might get scammed if you don't do your due diligence correctly, but if you make good friends with local partners or parties you will get the red carpet and PLIs.
Cadre-driven parties like the BJP, DMK, BJD, BRS/TRS, etc are organizationally similar to the CCP but other parties are more loose and disorganized, so having a local partner act as your firewall helps massively by pointing you where to invest, just like in China, where most western companies invested in Guangdong, Zhejiang, etc but ignored Hubei or Guangxi.
There's a reason why Israeli, Chinese, Japanese, and Korean companies tend to be fairly successful with their India ventures, because they're used to this kind of an operating model, and most American companies tend to have a first-gen Indian American or Indian educated in America managing operations with India.
