I think yes and no.
There's different ways of winning. Fighting proxy wars is not that effective. The US lost the proxy war in Vietnam but won the Cold War.
I think the US won because they demonstrated that a capitalist-democratic society provided a better quality of life than a socialist-command society.
I think to win long-term, your society needs to excel in freedom, education, safety, healthcare, infrastructure, cost of living, technology, business opportunities.
Over the last two decades, we have not invested enough in these areas and other places are catching up or surpassing us.
