It is very arguable that America's military is weaker than China if they have entered a conventional war. America being a war monger since the ending of world war 2 have knowledge on different types of tactics that their military have learned through experience and this is being taught in different courses in military schools. China's army does not have the experience on war similar to America. People also argue that China's military is only good in posturing and microphone threats hehehehe.
I completely agree that the Chinese military lacks experience since they've never been any kind of armed conflict (like a
weasel) but I disagree with saying US military has any kind of experience because they haven't been in any kind of
real armed conflict over the past 80 years either. Maybe the closest thing would be Vietnam war but the rest are just proxy wars and attacking weak countries with no means of defending themselves.
Iraq, Syria, Afghanistan, Libya, Palestine, .... were all either unarmed or disarmed when US regime invaded or attacked them. None of these cases were real armed conflict. For example by 2003 Iraq had an exhausted and defeated military after the dictatorship's brutal invasion of its neighbor Iran and it was torn apart due to a decade of US sanctions and various bombardment operations (after they were defeated by Iran and failed to fulfil US regime's objective of defeating Iran). The dictator of Iraq willingly disarmed his own military and by the time US regime started the attack they basically had nothing to defend against it. He even got rid of his missiles that could hit US carrier groups so when those carrier groups were bombarding Iraqi cities he had nothing to respond.
Due to capitalism disease, deep rooted corruption in the US regime that is controlled by arms dealers, ever increasing national debt that grows at the rate of $1 trillion per 100 days, etc. US military has fallen behind technologically and firepower-wise.
For example the same carrier groups that freely bombarded Iraqi cities could not do the same to the poorest Arab country called Yemen over the past 15 months. In fact when they tried it the armed forces of Yemen bombed the hell out of US navy and
incapacitated 3 carrier groups with domestically produced advanced drones and anti-ship missiles that are cheap while US regime spent tens of billions of dollars and failed.
For every ASBM this poor Arab nation can produce, China can produce 100... meanwhile the American arms dealers like for example Raytheon that produces about a dozen SM (anti missile defensive missiles)
per year can not even keep up with the defense. That's not to mention how useless these missiles are (as it was proven on first of October last year when USN launched its entire year's supply of SMs and failed to intercept even a single Iranian low-tier BM launched from 2000 km away at the Zionist terrorist positions in occupied Palestine).
The Xi of the Jin and the Ping might be very much afraid to begin a military war against America.
Only psychopaths and idiots
start wars against others regardless of the enemy's strength. Even the weakest enemy can deal damage which means wars are always costly and anyone with half a brain would avoid them.
