If we already have nukes, why would we need anything else?

Nukes prevent any war from happening between any powerful nation.

The only use for the other types of weapons is to participate in some other civil war in another country that we shouldn't be in.

So no, I don't care if we "fall behind" because we still have nukes and those are enough to protect us in the conflicts that matter.

Nukes are an instrument of last resort, but you don't want to get to the point where that is your only option. And it is possible that technical advances in missile defence may blunt this advantage.

Being able to prevent friendly (and even neutral) countries from being bullied or going over to the dark side is also important because ultimately the best defence against rising autocratic forces is to ensure a broad alliance of friendly, democratic countries who are secure against interference by unfriendly regimes.

If a country like the USA can have its elections manipulated, how vulnerable might smaller democracies be?

The CIA could most certainly help you answer that quite quantitatively.

> If a country like the USA can have its elections manipulated, how vulnerable might smaller democracies be?

This has to be a joke, right? The USA has been responsible for undermining democracy all over the world more than any other country.

This is a just a partial list that we are aware of. https://en.wikipedia.org/wiki/United_States_involvement_in_r...

It is also implicated (though not directly proved), that USA was responsible for Arab spring.

So, in the universe you are writing from, the Kargil War would have been an impossibility?

India and Pakistan aren't really powerful nations in the nuclear sense that the US and Russia are. I assume the person you are replying means powerful nation as "nation with a lot of nukes", which is pretty much only the US and Russia.

US Nukes: 7300

Russia Nukes: 8000

India Nukes: 90-100

Pakistan nukes: 100-120

Everyone except the US and Russia nukes: ~1100

Even if you restrict it to the US and USSR (and later Russia) there have been direct armed conflict, including both being on opposing sides in war (notably, but not exclusively, both Korea and Vietnam during the Soviet period, but also extending into the current war in Syria), though there have been political cover done to limit risk of escalation (e.g., Soviet Air Force flying NK-badged fighters and, initially, prohibiting use of Russian over the radio in Korea; Russian forces on the ground fighting, sometimes directly against US forces, being the “Wagner PMC”—a GRU-backed notionally-private group.) op

The US and USSR/Russia did fight a good number of proxy wars throughout the cold war and beyond but those are distinctly different than the kind of all out war I think the original poster was referring to.

There's a reason they were all proxy wars and they never escalated into direct conflict on the scale of WWII (or beyond), and that reason is nuclear deterrence.

But they did fight them, including direct conflict with eachother. Which answers the upthread comment “If you have nuclear, why do you need anything else?” which was supported with the claim “Nukes prevent any war from happening between any powerful nation.”

Nukes don't prevent “any war” from happening between powerful nations, though they do seem to have some utility in restricting the escalation of such conflicts.

(Now, you could argue that unilateral conventional disarmament would leave no choice but to escalate to nuclear war, which would improve deterrence and prevent even small scale conventional, politically-covered attacks, but that argument would be highly speculative.)

100 nukes is powerful enough.
