I think it's important to keep in mind the current capabilities of nations to conduct war. A modern war requires preparation. You need advanced equipment and the doctrine to use it, along with well-trained officers. And if you want to fight a war on foreign soil, you will need the infrastructure and logistics to supply your forces. All those things don't pop up overnight. The fact is that the US/NATO forces are one of the only military force capable of conducting an extended invasion and occupation of another country today. China has a strong military and navy, but it is largely positioned for limited operations in the South China Sea. Which isn't a knock on the Chinese military, it's intentionally how they have positioned themselves. In short, I think it's unlikely we will see another total war scenario in the current political climate. The only war I could see that unfolding is US/NATO forces attacking a peer or a close ally of a peer (like North Korea), and the US and Europe are so reticent of conducting an all-out war I don't think that will happen.
