In the short run, if we got new dear friends with nuclear weapons, then we have
he2 wapons.
In the long run, when we get enough land and sea area, we can do research
and in a proper place to test it. We are not idiots. Why we can't have nuclear
weapons we made by ourselves?
When we prove that we can occupy more land by only economic means, there's
the possiblity that China/U.S. will sell their nuclear weapon tech to us as well.
All in all, Japan has nuclear wapon actually. Don't 门缝里看人.
