18 generations of Pelosi?
No, I think you greatly overestimate the morality of American politicians.
Do you think Pelosi and her think tank did not anticipate that her actions would lead to China's occupation of Taiwan's territorial waters and airspace and harm the actual interests of the USA? No, she must know.
But Pelosi believes that her personal profit, such as rate support and fame, rank first. Her relatives' profit are second in order, for example, her husband. Her party profit are in third place, for example, the mid-term elections. And the national profit of the USA are only in the fourth place.
So do you think Pelosi will sacrifice her and her family for the benefit of the USA? No, soon Pelosi will secretly contact the Chinese govt and exchange the interests of the USA for her pardon.
Therefore, there will not be 18 generations of Pelosi. In a few years, China's sanctions against Pelosi will be sold by the Chinese govt at a suitable price.
Of course, in newspapers and television stations, Pelosi will not yield to sanctions. She will certainly act even more anti - China.
