Good. China should be nervous,
And the Chinese communist government took all the right steps to isolate and limit the spread of the virus in China, but did not prevent it from spreading to foreign nations. They closed the roads and trains but not the airports. That was a decision they made, knowing that COVID-19 would create chaos and destruction around the world.
God forbid anything serious happens to President Trump, but the situation with respect to China just moved from bad to potentially the basis for military action against China.
It might be necessary to simply seal off China from the rest of the world. I am sure our military could sink every container ship that left a Chinese port without much effort at all.
President Xi should be doing everything in his power to ensure President Trump's continued health.
