Yes, I do believe we will eventually come into conflict with China.
China is aggressively growing it’s military might, and could pose a threat in the distant future. (Not soon by any means.) They are one of a handful of countries that has the potential to launch ICBM missiles at North America, and that alone is something to worry about. Although we’d nuke their ass if they did, they still pose a threat as they gain more advanced technology.
However, I think that we’ll see a conflict between China and Taiwan long before a conflict with the United States. (Although a conflict with Taiwan could potentially bring the United States into a battle.)
China’s military is pretty much a joke in comparison to some of it’s adversaries. Although it’s the largest in the world with over 2 million people, it severly lacks technology, equipment, and training. I would hope for China’s sake that they didn’t get the balls to launch an offensive against anyone.
