1969 Sino-Soviet border conflict broke out in Zhenbao Island and other places. Because both sides have nuclear weapons, there is no large-scale conflict. In 2 1 century, border conflicts broke out from time to time between India and Pakistan, both of which are nuclear countries, but the border conflicts were controlled within a certain range.

After all, right-thinking countries know what nuclear weapons are. Once a nuclear war breaks out, the world will be destroyed. The future space will be broader, but as long as there are enough nuclear bombs, the destructive power is bottomless. Of course, there may be newer weapons of mass destruction in the cosmic era.
