The topic that I want to raise due to the current political situation is the number of working nuclear warheads in Russia. I've collected the indirect arguments that step-by-step exclude the possibility of specific amounts of warheads presence.
From them, we can confidently state that:
1) They do not have the declared number (4500+) of working nuclear warheads, simply by comparing the budgets allocated for the modernization of the Russian Federation and the USA.
2) They do not have working hydrogen bombs since the USA has updated this arsenal three times, and Russia has not produced tritium since the 90s and has never purchased it.
3) They do not even have a thousand nuclear warheads since the Soviet military legacy underwent reconversion and closed down, unable to withstand competition, due to which, unlike the USA, the entire production chain broke, which forced them to start looking for new suppliers. Also, thousands of specialists in nuclear, computer, and other fields are needed to establish production, which is an unobtainable resource. It is also worth considering the lost decade of the 90s when specialists did not receive salaries for half a year, education in these areas was reduced (and is being reduced), trained specialists died or left, and the designs of nuclear bombs were highly classified under the USSR, which guaranteed the loss and need to rediscover the necessary technologies (like in the USA). Finally, it can be argued that the production of nuclear weapons was never put on a conveyor belt since there is no evidence of this, even though the access to this information should have been provided.
4) If we compare the costs of maintaining the operability of nuclear warheads in the US and Great Britain with Russia, then we can say that Russia did not have the money even to sustain and modernize hundreds of warheads. Considering the technological gap between the USSR and Russia, we can say that the assembly and modernization of each warhead have to be carried out manually in "artisanal" conditions. From all this, we can already set the maximum production bar in ideal conditions in the order of tens. 
5) Next, it is worth considering the factor of systemic corruption, due to which they steal wherever they do not check. In this case, Russia has not conducted nuclear tests since the 1990s. They could show the bosses a phony and steal from the provided budget. Moreover, the dictator does not care about the number of working warheads. Only the fear of them is crucial. Therefore, control is not so important - only high-quality reports are. From this, we conclude that the maximum actual number of modernized warheads is measured in units. 
6) There is no confirmation of the absence of working nuclear warheads. However, given all of the above and given Russia's current situation and the fact that its red lines have been repeatedly crossed, which, according to the Russian nuclear doctrine, should be followed by a nuclear strike, which not only did not happen but there was not even a hint of any activity in terms of moving the nuclear arsenal, even to conduct nuclear tests on its territory, it can be argued that the stockpile of working warheads is so tiny that Russia is not sure that even one of them will go off, which is why it is trying not to risk it. Russia is obviously trying to maintain a bluff, which is why it has classified data on the number and condition of nuclear weapons.
7) In connection with the recent classification of this information and the systematic lies in the reports, it can be argued that the Kremlin did not know about the state of nuclear weapons up until recently when the escalation required retaliatory measures. Because of this, the US, whose spies sit in the Kremlin, probably did not know either. 
8) Going further, the quality of the equipment for testing these models and the equipment of control centers raises serious doubts since it had to be created from scratch. To the lack of real and virtual testing, we add the percentage of defective homemade warheads and get the number of working warheads (according to virtual tests) in the range from 5 to 10 and the number of really working warheads from 0 to 2.

So far, I do not know any contradicting facts to my statements. Which is why I want you to check my arguments on the matter of logical reasoning, prove or disprove them given the knowledge you have, and overall give your own estimate of the number of working nuclear warheads in Russia.
