Where does China "Want a War", exactly? China hasn't been involved in a war since 1979. We've been involved in several.
We invade countries, the Chinese help people build roads and airports.
Guang gun is a major reason. (Not that you know or care what that is.)
If you were not a chicom homer you would know about the aggressive threats of war china is making toward Taiwan
Or the fortified islands china is building in waters owned by the Philippines and Vietnam
Xi has mismanaged the chinese economy
and he needs a diversion
He is also dealing with an excess of young, unmarried and unmarriable men, due to the one-child policy.
