Theory:

Russia and Ukraine will sign a ceasefire or peace agreement soon. Ukraine has ran out of countries willing to give it money.

After this, China will invade Taiwan. They wait for Russia to be finished purely for optics on the global stage. They don’t want to be both engaging in military campaigns at the same time.

Either shortly before or after China invades Taiwan, Trump will be arrested by the Biden regime.

Taiwan would just be their ideal distraction. Markets will tank, will provide them an excuse for their failures etc.
