Although technology determines tactics, it is people, not weapons, that determine the outcome of a war. The Development of the B21 Bomber by the United States sounds like it has a lot of high technical content, and it seems that it has not yet been witnessed.

Although technology determines tactics, it is people, not weapons, that determine the outcome of a war. The Development of the B21 Bomber by the United States sounds like it has a lot of high technical content, and it seems that it has not yet been witnessed. But the victory or defeat of the war is by no means dependent on one or two new weapons and new equipment, but on the wisdom and courage of people. The Korean War is an irrefutable proof that the US military is armed to the teeth and has not been defeated by the chinese and North Korean troops with ordinary equipment. Moreover, the United States' high-profile display of its new equipment is likely to cause a new round of arms race in the world. The Americans are neither generous nor nurturing, and the whole world has stirred up the United States.
