Ok, I apologize for jumping to conclusions. What is your opinion of the childless? And if what you claim is true, what if anything do you propose to address the problem?
So, you don't think that China's numbers gives them an advantage over us, now that their military hardware and training are improving?
Sure, if we wanted to invade China. I don't think they are anywhere near being able to successfully invade and hold U.S. territory.
Given the commitment required to be a decent parent, it should be entirely voluntary. However, people also need to be honest about the larger societal impacts of not having children.
For example, the birthrate of immigrant Muslims versus the native European population does place European civilization at risk, IMO.
That requires European society to make choices (1) encourage childbearing by natives, (2) limit childbearing by immigrants, (3) limit immigration, (4) force integration, or (5) capitulate.
