Wait then how the fuck are b52s supposed to work in a ww3 nuclear 2nd strike option?
Because we don't know how a nuclear exchange would be fought. Whether it would be just a few limited nukes going off in tactical locations, which could escalate further (say we bomb your army, so we bomb two of yours and so forth). Which means you want as much stuff nuclear capable and ready to deploy arms such that in a prolonged nuclear exchange, you're able to mount a response. Hence why Nuclear Submarines are so important.
The reason why such a nuclear exchange can even occur is that we can identify the trajectories of an inbound warhead via satellite, and we can use metrics such as the doppler effect, light and on so on to know where it is roughly heading. So, it may not always be the best idea to aim for Silos on a first strike, or an airbase if you're only wanting to do limited damage. It is very much a case of "I'm ready to use my nukes now so shut up, and get ready to talk".
It is just that we like to think of nuclear wars as being a full counterforce and countervalue campaign which really is not the case.
I find it funny how some of the bric simps live in a parallel universe.
Presuming China's military is at least competent, they would actually have quite a good chance when it comes to fighting Taiwan primarily because they have the benefit of force concentration, and can overwhelm US aligned forces in the region, presuming their equipment is of a sufficient quality and they can maintain manufacturing capability (which they have been building up, and China does have the largest supply of rare earths which are critical in modern military arms).
A war with China would allow China to focus all of their assets on Taiwan, and the surrounding islands. This is the main concern for planners, and is something I will continuously return to. This is on the basis of America having sufficient material they can deploy to counter China.
See why it was necessary for strategic planners to begin taking out threats elsewhere? Venezuela, they are in a position very close to the States. Something that could be a great fortress, and to keep US war planners in a "will they, will they not" kind of situation. Same with Iran, who has been willing to exert influence, and threaten western interests and have shown their insanity with throwing munitions all across the Middle East. Say what you will about Europe, they are at least prepared to fight Russia and the US would be less required to bring forces for that reason.
This means that the US has a lot of different theatres to contend with, which means diluting their naval strength so that any major adversary would be able to have a fleet in being capable of forcing the US from bringing assets away from anywhere. If in the past the US would have liked to keep a carrier strike group in the Middle East because of Tehran, if that threat is neutralized then it can be redeployed elsewhere. The US is now back at only 10 carriers in service because of the retirement of Nimitz, which means they are waiting on the JFK to get back to 11 ships, and are currently down 1 Amphibious Assault Ship (the USS Bonhomme Richard which had to be scrapped following a fire, that ship was capable of carrying 20 F-35Bs).
(I believe I've explained this logic before but I digress, the entire point is to ensure that America is on the best footing to fight China)
In an ideal world for China, Iran would have been in a great shape. Russia would have been a constant point of consideration for NATO and distract a lot of their naval and air build-up. Venezuela would have just been sitting there. But now, the conditions are now gone and the US is able to be a lot more lenient in keeping stuff there. This is not the case, and now China will have to second guess whether or not they have ample numbers. Of course, as I've already mentioned they have the home turf advantage which means they get access to land assets. Naval aviation is less critical.
What the US is doing now is basically dealing with the problem that came about with the Anglo-German naval arm's race, where each country was rapidly building up their naval assets. Tirpitz having believed Germany only needed 2/3rd of the size of the Royal Navy to actually threaten the Royal Navy in the North Sea, given Britain had the whole Empire to worry about. The British instead chose to bring all their major ships to the North Sea, and any attempts of Germany to break the blockade didn't work. This seriously limited the Mediterranean and other fleets, but thankfully due to British diplomatic maneuverers at the time, it was not all that much of a worry. Why? Well, Britain was friendly with Japan and basically was building their navy at this time. They were doing same with the South American countries. France and Russia were on their "side", and Italy was Italy.
This is also why Britain was unable to send a major naval force to the Pacific in the second World War until pretty much end. They had to contend with both Germany and Italy in the second World War. As first, the British ships were built for the Atlantic (hardened flight decks, aircraft tenders, more guns on their ships) and land based aircraft like the Stuka which could divebomb. Second, because of the Washington Naval Treaty and how it set the Imperial Japanese Navy at around 60% of the size of the Royal Navy (not like Japan cared at the end). If America didn't get involved with Indochina and embargoing Japan, Japan would have been able to do as they pleased. against Britain, the Dutch and whoever else remained (at sea at least). And the ships that Britain did send in the onset of the pacific war? Well, Force Z wasn't all that really strong, with a treaty Battleship (Prinze of Wales) and a really outdated WW1 Battlecruiser, HMS Repulse which only had 6 WW1 era 15 inch guns. Naval aviation was not sent. The only over main British capital ship that would see use in the pacific would be Victorious (an Illustrious Class Carrier) for a brief period following refits in the US after 1942.
But then again, it would very much be a pyrrhic victory because they'd be blockaded in major trade routes and would not have the logistical capacity to wage global war. Even the Royal Navy and French Navy is better than them at it.
literal fake news
czechia is a landlocked country and has no navy
First, rivers exist and some countries use them to say they have a navy, such as countries in the Danube or the Rhine.
