Why is an idiot calling experts idiot?
The article is based on this report
https://s3.amazonaws.com/files.cnas.org/documents/CNAS-Report-Work-Offset-final-B.pdf written by Robert O. Work and Greg Grant. Mr Work has served as Deputy Secretary of Defense and Mr Grant worked for the Department of Defense too.
If these experts are so wrong then i want to know what the background is of UKBengali, F-22Raptor, XTQ1999, Viet who appears to know more than these experts with years of experience working in the Defense department. The report also describes clearly that US has never dealt with an opponent as powerful as China even Soviet Union cannot match it during the Cold War.
Actually, this article have nothing in common with the one that Works and Grant wrote on Center for a New American Security except that quote, that is China is catching up on Military Technology in par with US, however, if you really read the CNAS article. The author suggest that this is a "Desired End States" the Chinese wanting to be. Not at all currently achievable now.
The CNAS article is about how China can beat the US and traditionally the US is unbeaten in term of Technological and Numerical advantages since WW2. However, by focusing on "rouge" nation (Possibly mean Afghanistan and Iraq) US stopped focus on peer to peer competition, and that result in a technological gap being closing down by the Chinese. With China a designated enemy US has never seen as both being Technological Advance, and Economically sustainable, which Soviet Union is not.
The CNAS article suggest that there are 3 stage the Chinese Military would like to achieve.
1st Stage - Would see the Chinese military compete with the United States from a position of technological inferiority
2nd Stage - Would occur when the Chinese achieved a position of rough technological parity in guided munitions and battle network warfare, making it far more likely China might be able to deter a U.S. military intervention in the East Asian littoral
3rd Stage - Would represent the desired end state, when the Chinese military would establish a position of outright technological superiority over U.S. military forces
At this current time, China is still at stage one.
The CNAS article also identify 5 things the Chinese Military do to try to overlasp US in term of technology, I am not going to write it down here. You need to read the article to see.
On the other hand. The article OP refer to takes point out of the CNAS article and further elaborate on its content. And in most case, contradict what the writer wrote on the CNAS article. For example, while the Chinese Navy is building ship on a massive scale that US and most other country is not. CNAS article indicated that Chinese is merely playing catch up and try to modernize its fleet.
I do not have a military background, but I have a Law Degree and an Accounting Degree, so I am perfectly capable to read and digest an article, and I am telling you, the OP article is not base on the CNAS report by Works and Grant. Not even remotely. Works and Grant article is about how China can defeat the US in the future, not China can defeat the US now and there are nothing the US can do about it.
