And US will drastically escalate if Pelosi is killed. No nukes were used back in the Cold War. No nukes are used now even though Ukraine has killed tens of thousands of Russian troops, mostly with US supplied weapons and intelligence.
In Ukraine the conflict is between Russia and the Ukraine. If NATO entered the war nuclear weapons would be used, as Putin has repeatedly said. In Vietnam America fought Vietnamese with Russian and Chinese weapons and intelligence.
Neither situation is comparable to what America is threatening right now. When a U2 was shot down over the USSR, did America "drastically escalate"?
No, knowing who controls world media today, China will be painted as the bad buy. People would be crying bloody murder, and there would likely be sanctions and condemnations. China's allies would likely want to remain out of this mess or put out symbolic statements that don't mean nothing.
More deluded American centric thinking. CNN and Fox news play no role in setting international law. China already is the bad guy according to American media.
As for sanctions, good luck with that. If anything China imposing sanctions on America is more likely than the other way round. Nothing in the west gets made without Chinese components.
Can someone explain to me why this is considered to be such a big issue when Newt Gingrich visited Taiwan in 1997 and it wasn't considered by the PRC to be some huge affront? Not only did Gingrich went, but he brought a huge entourage with a dozen members of Congress. I remember in late that year Jiang Zemin actually visited the US, had a state dinner with Bill Clinton, and put on a tricolor hat. The only thing is that Pelosi is in the same party as Biden whereas Gingrich was a Republican, but in terms of official US titles they were both Speaker of the House, and Gingrich was as much a member of the US government and in line for succession as Pelosi is.
Simply, China is stronger now and can defend its borders today in a way it couldn't in 1997.
A country can be as inconsistent in its border entry policies as it likes. America can't use prior examples of border violations to continue violating China's borders.
