China gave Pelosi multiple "last chance", just so she could make them a joke. Taiwan is a Chinese territory and the US roam free in Taiwan like the Chinese don't exist. The Japan surrendered because US gave them 2 nukes, not because Japan is given warning from the US.
Did China ever say cross this line and it’s war? China said there will be significant consequences and there were.
And serious countries don’t throw nukes lightly. None of us would be alive anymore if countries behaved so childishly.
China is giving the US chances to course correct before China enacts countermeasures. So long as the actual war-triggering red lines has clearly and repeatedly set out are not breached, China will continue to salami slice and make war prep, but it will not start a war lightly or be rushed into it. China will go to war when it has no choice not to, it’s actively preparing for that day to minimise the cost to China, but it’s not something to rush into or actively want to happen.
