Your ignorance of geopolitics laid bare for all to see.
I don't personally feel that China should be our enemy purely because I view our relationship with them as transactional. I also view it as foolish to pick a fight you cant hope to win with a superior force. That's not being weak, that's just common sense. Whether we like it or not, China is a peer competitor with the United States and should be recognized and treated as such.
However, also know though that we are divided by the World's largest body of water and we have plenty of other Countries on China's side of the World that also have interests that align with ours. So we can afford to use additional brinksmanship when dealing with China. It also makes sense to not do anything with them that undermines our relationship with the other very powerful Country that exists right next door to us.
Likewise, whether you personally like it or not, we live beside the most powerful Country in the World. Just that fact alone necessitates we develop an incredibly close working relationship with that Country, it's also a bonus that many/most of our interests are also mutually exclusive. It also dictates that we must align with this Country on many issues or face consequences. Again, that's just smart politics and sensible strategy.
I personally view Russia as a bigger immediate threat than China. Unlike China which has shown a willingness to want to at least be part of the International System, Russia is a Rogue State that is strong and uses that strength to act like a real destabilizing force in the World. They have shown that they have the ability to undermine our interests and should be challenged because of it.
