Corsica?? Dude, don't try to be more ridiculous than you already are.
If they force us to use nukes - they'll be forces to pay for it. Right now they can f#ck off almost scot-free (just losing their zone of influence in Africa). After the very first nukes are fallen - they will give Corsica. After more nukes dropped - there will be war until unconditional surrender of the French leftovers.
The same thing is right for America. If you want to take Crimea and Novorussia, your more or less equal bet in the nuclear gambling is Alaska and California. If you want to take Russian lands - you should understand that you are going to lose yours.
I see. So, you haven't, either. And know nothing about the site.
I believe that information in Wikipedia about NTS and Vegas is more or less correct.

The Nevada National Security Sites (N2S2[1] or NNSS), popularized as the Nevada Test Site (NTS) until 2010,[2] is a reservation of the United States Department of Energy located in the southeastern portion of Nye County, Nevada, about 65 mi (105 km) northwest of the city of Las Vegas.
Formerly known as the Nevada Proving Grounds of the United States Army, the site was acquired in 1951 to be the testing venue for the American nuclear devices. The first atmospheric test was conducted at the site's Frenchman Flat area by the United States Atomic Energy Commission (USAEC) on January 27, 1951. About 928 nuclear tests were conducted here through in 1994, when the United States stopped its underground nuclear testing.

Las Vegas,[6] often known simply as Vegas, is the most populous city in the U.S. state of Nevada and the county seat of Clark County. The Las Vegas Valley metropolitan area is the largest within the greater Mojave Desert, and second-largest in the Southwestern United States.[7][8] Las Vegas is an internationally renowned major resort city, known primarily for its gambling, shopping, fine dining, entertainment, and nightlife, with most venues centered on downtown Las Vegas and more to the Las Vegas Strip just outside city limits. The Las Vegas Valley as a whole serves as the leading financial, commercial, and cultural center for Nevada. According to the United States Census Bureau, the city had 641,903 residents in 2020,[9] with a metropolitan population of 2,227,053,[10] making it the 25th-most populous city in the United States.

And what should I get from this link?
For example this? Defence priorities - deterring strategic attacks against the United States, Allies, and partners. (among others)
Remind me, wasn't it you who argued that the US wouldn't respond on Russian nuclear attack against France or Germany?
What else do you want to 'prove'?
So, you didn't read it.
Ok. Let's play a comic scene (just to add some contrast to the grave situation). I don't believe in crazy dictators, but why not.

The fried Chicken.
Macron: I wanna send our forces in Ukraine!
Zelenskiy: Don't do it, I don't want your soldiers, money (or weapon to be sold) would be quite enough.
Macron: Shut up, you just want to steal our money. We gonna fight and we gonna win!!!
Zelenskiy: Ok then. Help yourself.
Biden: Don't do it. We don't need to fight them directly. It's reckless and stupid! Just join the sanctions and wait until collapse of their economy!
Macron: Shut up, you coward! I got tired of all this BS! Sanctions, economy! Let's crush their armies and put them on their heels!!!
Biden: Ok then. But you are on your own since now.
Putin: Don't do it. We don't want to genocide French people.
Macron: Shut up, you mazaf#ka! You are bluffing. You won't launch your missiles!
Putin: Ok then. If you wanna commit suicide we can't stop you.
French forces deployed in Odessa. Russia bomb them, kill most of them.
Macron: my fellow frog-eaters, we should fight those Ruskies and send more forces in Ukraine, now in greater number and better equipped.
Putin: ask Parliament's permission to use force against France. The Parliament allow him. Putin declares large drills of Army and MChS (including partial evacuation of the cities) and calls his people to arms. Russian ambassador in France declares ultimatum to the French government: "One more soldier in Ukraine and we are officially in war."
Biden: My fellow Americans, you have nothing to worry about. France is on their own and we are not going to fight a war with Russia whatever happens. Our Defcon is still on the level 3.
Macron: Ha-ha! Nobody can stop me!!! I'm reincarnated Napoleon, but this time I shall prevail!!!! Send more soldiers to Ukraine! Ignore their nuclear threats!
Putin. Press small red button. French nuclear bases destroyed. Ten thousand of French soldiers and sailors are dead. No civilian casualties.Their last ballistic missiles sous-marin is killed by a Russian attacking submarine.
Macron: kill himself. Mary Le Pen is a new French leader, agreed on the generous Russian peace terms. She hate to lose Corsica but it's much better than lose the whole France.
And now, Ladies and Gentlemen, we are going to the final Biden's choice....
His options are simple:
1) Do not interfere and allow Russia and France settle their peace treaty on the mutually acceptable terms.
2) Order direct and immediate out of blue attack against Russian cities. (And this, definitely means suicide for American cities either).
3) Order to raise Defcon level to 2, evacuate American cities and join negotiations with Russia, risking that the Russians will read it as a preparation for American first strike, and will preempt America, by attacking them first (as Russian cities are already evacuated, it means that American retaliation strike will kill less than 10 millions of the Russians).
What should he choose, my dear friends?
