Future technology might disagree with this
It wont tho.
Tank uses 100 times more fuel than a car, and jet plane uses even more during flight.
The batteries needed to power them would take days to charge, and would have to be much larger than the ones currently used in cars. Their range would be much shorter than the ones which run on fuel. So a military electric plane would fly for few hours and then charge for 2 days, which is about as bad as it gets, even if it was possible to make with small enough battery.
I don't know what your alternative is to expanding nuclear energy.
This isnt really about nuclear energy, but about capitalism racing to deplete resources. Due to this race, fuel will run out by 2050 or 2060. Then the world will change completely, especially in military sense. All today's militaries rely on fuel to power aircraft, tank and transport. Basically, the country which saves up most fuel will have huge advantage over any other country in terms of military once fuel runs out. So essentially, governments which use planned economy will save fuel while those relying on capitalism will waste fuel until they run out of it. And fuel is the best possible energy for military planes and tanks and transports. The other sources are far worse.
Chat GPT is giving me tens of thousands of years.
Current supplies of useful uranium will run out in 200 years under current consumption, but if everyone switched to nuclear, they would run out in 20 to 40 years. Now, there are some theories about converting useless type of uranium to useful, but those are just theories. Most theories which sound too good to be true usually are false.
