From my experience percentage of Indians with good English exceeded that of Chinese in Silicon Valley, I always thought this observation was due to that fact.
No, you are putting words in my mouth and being very reductive. Majority of powerful people is not jewish nor zionist, but there is probably a lot of zionists amongst them. And no, not all jews are zionists, nor all jews are in powerful positions.
The simple truth is there are a lot of zionists in powerful positions both in terms of governmental and monetary. Open wikipedia and look up cabinets and powerful people in US government since WW2. Pay attention to their ethnicity; even if half are zionists, that's a lot of people.
Edit: people downvoting this, first part of the comment is just facts, second part is plausible speculation. Why are you downvoting?
