>Simply because if Russia loses men at a rate of 50:1 the US could still find those losses unpalatable
The crux of the matter is there are few nations on earth where life has so little value as Russia. Their leadership has no trouble sending or convincing 10's of millions to go and die. It is my belief Americans and Europeans still don't understand this and if this war was to spill over from Ukraine into Europe it would be a disaster no different than WWII. Yes, USA/Europe/NATO would win but it would cost them millions of lives. Putin has already said if I run out of men I will send Women.
>Frankly I’m confused why we don’t have these things for big static targets like a drone that independently navigates to a rail line, drops a mine and leaves for the train to blow up next time it shows up.
I think the West believed that they could just use their air power to destroy these targets but failed to realize that they have never really fought an enemy that had a serious air defense. Iraq was using systems from the early 70's that were easily defeated.The USA doesn't even have a basic drone like the Iranian Shahed drone that could be produce in mass, they also have no answer to stopping them efficiently.
America can not win a conventional war with China, that is a guarantee. The Chinese could field millions of drones and a endless supply of men and with the support of Russia, North Korea, Iran, etc, would have no problems defeating the US/West. The second Americans couldn't buy a microwave, iPhone, or video card and millions of other things, they would lose their minds and surrender......
