This posture change will keep pace broadly with the American domestic chip fab industry.
This is very obviously true, since China is a nuclear power and has ICBMs as well. We won't be involved in a hot war with them for the same reason we have been avoiding that with Russia.
So support via the former will always be the more tenable position for a democracy.
I can assure you that if the everyday American saw in line item on their paycheck called "Ukraine War Tax" the public would be much less supportive, but since all the money is either printed, to debt then there is a disconnect between government spending, and the hidden tax of inflation everyone is paying but pretending to just be "greedy companies" and not government spending that is the cause
Republicans want the Presidency in 2024, and turning their base against Ukraine is going to be a pillar of their strategy.
Russia can also do what it likes because of the constant nuclear threat. Russia has nukes that work, whereas the likes of the UK has a single nuclear sub that occasionally gets stuck on a sand banks. The Russians probably know where it is at all times.
It was one EU country in particular that was very vulnerable for a few separate reasons for the Russian gas politics, but they have seen the errors of their ways at long last.
Dependence on Russian energy is significantly reduced and there more than every intention to reduce this to zero. Note that the intention was always there, gas was only ever a stopgap between now and fully renewable.
Does it?
Nominally, Russia has roughly the same number of nukes as the US.
The US military budget is 700bn/yr and it spends 60bn/yr in maintaining its nuclear weapons. So 60bn/yr is a good estimate for what it costs to maintain a US/Russia-sized nuclear weapons arsenal.
Russia spends 60bn/yr on its military in _total_. However much of that goes into maintaining its nuclear arsenal is clearly not nearly enough. By all accounts Russia can't even maintain its trucks. Most likely the budget for nuclear maintenance is "disappearing" the same way that much state money disappears in Russia. Surely no on believes that Russia has been spending 60bn/yr since the 70s, when the last nuke was detonated.
Russia no longer has nuclear weapons, you heard it here first.
