It has already cost China, in terms of world opinion. They are now the country that intentionally, or unintentionally, released a plague upon mankind.
Even their friendlies are and will back away from them. They stand alone with their other terror state, Iran.
They have done themselves in on the world stage. And their may not be nukes coming their way, but economic isolation is. China is screwed.
Democrats are incredibly stupid. But even stupid people love their mamas. And they don't like it when they die from the rona and they find out China did it.
Trump just has to let the world know what really happens. And, as per Q, he doesn't even have to tell they did it on purpose (which they did). Trump is very smart and a great President. We are lucky.
I think you are going to be very disappointed, if and when the truth comes out.
China did not do this. Trump has not accused China of doing this.
Trump did say, hardly noticed, that Xi is helping to find that information.
