That's the funny thing about modern military tech, it only really works correctly in peacetime when the wars are fought against poorly equipped insurgents & rebel forces. "Stealth" only works on very old radar systems, any 1st world country has the capabilities to detect a B2 or an F35.
After the second month of conflict, the only equipment left would be mid century jets that can be quickly built in single factories, without the complicated supply chains that F35 was built around. That's what matters, mass production and numbers - not $2B jets that can be shot down by a $100K missile system strapped to the back of a truck.
And don't forget the networking. It won't just be the one targeting radar; networked missile groups have existed for decades.
This idea that Russia and China can't "lock on" assumes that the Russians and Chinese are idiots. They've been busy trying to improve the odds of a stealth kill ever since the F-117A went public, and probably before. LO helps, but it's not magic.
This is why everyone in the world is queued to order F-35s: it's the world's only operational multirole stealth fighter you can buy, and it has no peer adversaries yet. Goes against the popular Internet wisdom of how crap F-35 are, but they sell like hot cakes.
The S-400 variant is claimed to be effective against LO aircraft, but since only Russia, China and Turkey operate the things, we cannot say either way. We definitely cannot claim it's ineffective against LO aircraft.
The struggles with S-500 are well documented, much discussed on Russian arms nerds forums and absolutely have all to do with the challenges posed by F-35.
Where the original claim comes from -- that Russia and China cannot shoot down an F-35 -- is beyond me. It is as daft as claiming that S-400 makes stealth useless. I take issue with such confident grand claims.
After a week, they will still have many of their fancy planes, and, likely, will have destroyed a lot of your infrastructure, killed your pilots, etc.
I think you need both fancy planes and the ability to rapidly ramp up production of less advanced weaponry.
This is all assuming it's a total war without nukes though, which is fanciful.
A conventional war between nuclear powers over a third country (Taiwan?) could maybe possibly happen by attrition, but more probably by attrition of war morale, rather than war materiel.
Saying this does not make it true. Warfare is far more complex than you're making it out to be. Care to back up this statement with an explanation?
There is no good answer once war is on the table. Keeping war off the table should be everyone's priority, but unfortunately it only takes one evil dictator to force you into war, so peace isn't always possible.
I mean super-powers with nuclear weapons just constantly have to fight of these dictators.
What an odd as argument. This has literally never happened.
But in 1990, China cancelled the deal unilaterally, despite it being the only access they had to Western military tech. Ultimately it went with Israeli and Russian sources. Why? The US arms exporters were running into massive cost overruns and development delays. China thought it was some kind of intentional sabotage, but it was nothing of the sort: it was just the general fucked-upness of American military procurement running into the realities of a culture unused to that level of fucked-upness.
An international arms embargo couldn't accomplish the disarmament of China of American weaponry, but the brokenness of the American arms industry could.
Shifting the power balance is unlikely to result in a safer world for most.
It has been hotly debated on if mutually assured destruction is actually why we haven't got into a nuclear war or not. You can take either side of the debate with no way to know for sure who is right.
