Because in America's political system, popular belief has an impact on government policy. China would be in a much better shape if more Americans saw it as benign, rather than as a threat and adversary. The speed and comprehensiveness of the ongoing anti-China move in the US government is due to China having no friends in the US, when it easily could.
No, just the opposite, because actually the irony is that in a so-called democratic government where the government has to resort to false flags, propaganda, and other CIA-like techniques to drive political agenda whilst still maintain the illusion of freedom/ democracy for the populous, its in fact top down governmental policy that trickles down "Inception" style as common themes under the labels of "freedom, democracy, etc" to give the people the illusion of choice whilst on the backend its always been the power elite running the show... If anything, democratic governments have to be more deceptive to their population because they have to smooth out the cogitative dissonance whenever policy/interests don't align with purported values/propaganda. Do you think the average American knew anything about Huawei before Trump, at the direction of the Deep State (as he calls it) embarked on his campaign against Huawei and 5G? American people don't see China as benign because the American government, its intelligence agencies and the media arms of the government all take directives from above to start China bashing as its containment effort of an ascendant China, nothing less and no more. AT&T was about to strike a deal with Huawei to offer their handsets /smartphones before US gov stepped in at the last moment and put a stop to it. I suppose that was something the American people decided too at the grassroots level? No, its clear cut case of top down government intervention / state intervention against private corporate interests... and it most certainty wasn't something the American people were lobbying their government to pursue.
I'll be honest with you, I think either you are trolling or you are incredibly misguided and naive in the workings of geopolitics. Focus on lithography.
