There were no questions, except agressive "Really?", so I decided to skip the points. The thing is that the original author tries to put a nationalistic mask on science, i.e. "the X was invented by country Y", which is a fallacy suitable for populist debates. Science doesn't happen in vacuum, and scientific "achievements" are usually called "contributions".
Regarding your questions. 1) Three scientists received a Nobel prize for their work on lasers, you can check the wiki for names. 2) About the TV: my bad, A. Zworykin has been working in the US on the TV problem --- it's hard to trace everyone who emigrated due to the Soviet massacre. Anyway, you can find experiments, etc. for example, by Leo Theremin.
