As an Asian and whose country is under constant territorial threat from the bully China, this particular issue is very important for me. But I cannot tell whether or not an ordinary American finds this specific issue equally important that it may determine his/her vote.
I am from India, and my country had a major unprovoked territorial fight with the Chinese a few weeks back. For Asians, Chinese aggression is a big concern. Not sure whether the same will be reflected in the United States, because they don't have any direct territorial dispute with China. At least in this case, I have to say that Trump is more effective when compared to Biden.
China has become an expansionist. Their government is expanding to your country, to the South China sea and they have passed a security law in Hong Kong which removes some of its citizens' freedoms and rights. It also has concentration camps of uighur muslims.
When was the last time a country acted like this and which country was it?
