Japanese technologies?

Question:

Sorry, I've deleted the previous question. I apologize to the respondents of that question.

This is only a survey based on assumption.
(1) What do you do if you invent the following technology?
- It is an epoch-making technology which is applicable to medical science and environmental issues. It will save many people.
- It is also an epoch-making technology which is applicable to weapons of mass destruction. One country is actually developing the weapon, but it is a fantasy now. But, it won't be a fantasy if they got this technology.

Do you quit studying it? Do you sell the technology to the country?

(2) What do you think about the following cases?
- Japan monopolize the technology.
- Japan never export the application products to foreign countries.

Note: The technology does not mean a product but a core technology which is applicable to many things.

Answer:

Well, your question seems to be too heavy (specialistic) here at "Japan" forum...
I'm far from an engineer myself, but a friend of mine in Japan runs a big business concerning " epoch-making technology which is applicable to medical science and environmental issues", and he's very successful. (Although, it's now international business, he hasn't dealt with weapon) If you're interested, please e-mail me.
Yeah, all products had required some technology when they were produced. And once they come on the market, the technology must be protected somehow...
