Several nations begin warring with one another for the last stores of fossil fuels, namely oil and uranium. Known as the Resource Wars, fighting begins in April of 2052 and continues until October 23, 2077. China invades Alaska in the winter of 2066, causing the United States to go to war with China and using Canadian resources to supply their war efforts, despite Canadian complaints. Eventually the US annexes Canada in February of 2076 and reclaims Alaska eleven months later. After years of conflict, on October 23, 2077, a global nuclear attack occurs. Nobody knows who strikes first, but in less than two hours most major cities are destroyed. The effects of the attack will not fade for the next 100 years. As a consequence, humanity lives in underground Vaults though some people affected by the radiation live topside.

Fallout

Seems plausible

Did you ever see Jurassic Park? Raptors are smart.
Also, the bigger dinosaurs could easily get to the third floor.

I had a dream like this once. The answer is simple... Grenades and lots of them.
Also, Guns. Lots and lots of really big guns.


If the sun is what does us in then that would be awful boring.
If we're all gonna die, then we should at least die in the most fucked up way possible!
That's right... mutant wiener dogs!

The sun turning into a red giant is nothing short of spectacular. Granted this is in approx. 4.5 BILLION years. So we have some time. That being said, I'm sure some statistics expert could give me the actual numbers. But an asteroid is FAR more likely than anything else, due to the sheer size and number.

Guns? Really big guns. Sweetie a fucking revolver can barely penetrate a bear skull. A 50. Caliber would bounce off the stupid assholes known as Dinosaurs.

No.. Just no. The US annexing Canada? Unless the US wants a lot of the world up their ass they wouldn't dare put a soldier in our soil. besides by then the Canadians will have owned the Carribean and Alaska. Maybe Vermont and Maine too. Michigan too. Besides by then Canada will have trade and less dependant on the US. SUCKAS! We got the Carribean and ya'll got nothin'!

Well, sweetie, you obviously can't tell a joke if it walked up and slapped you in the face because I've been joking this whole time.
Christ, you're all too serious about this - esp. considering I'm not even the one who mentioned dinosaurs in the first place. I mean really, I have hunters in the family, I know what can kill a bear, deer, moose, whatever and what can't.
I mentioned zombies... which are way more likely to happen. Gosh.

And quite obviously you don't know just how many powerful guns are out there. Geez!

By the way, a 50 Caliber is baby stuff compared to what I've seen.

Odd considering no one really cares about Canada. If we were to take over Canada then we would control all of that, not you.
Alaska? Oh please, if the US didn't own it then Russia would because in case you don't know this - Russia still wants it on account of how much oil it has, which ironically is how we came to own it (because they found it useless up until we found oil there).
And you can have those fucking worthless states.

Though I'm curious how you'll come to get them considering Canada can't fight their way out of a paper bag.
Believe me, if we wanted Canada, you would have already been blown off the map already. The thing is, we just don't want it.

Also, the same could be said for other places as well, save for maybe England and Russia - they would prove most difficult to attain.
You see we have the technology to stop weapons, and destroy them before they even come close to us. And currently we are the only ones who have it or even come close to having it as we are the ones developing that.
Meaning, we have a defense. But we also have an offense.

Oh but seriously, we don't want Canada - it's fucking useless and would offer nothing to our gain. Unless of course you're hiding a bunch of oil up there.

Canada, owning Alaska! Ha! You think it doesn't work both ways?! Alaska is not only a territory of the US but is also a state meaning if you dare to get it, that would mean war as we sure as hell wouldn't give it to you.
Now, Russia we might give it to because Russia would use it properly as Canada wouldn't. Because Russia would drill for oil there in a heartbeat.
Besides, Canada wouldn't last 2 seconds against the US because your country is full of wimps. Esp. considering it took you people fucking forever to become independent (but even now you're not 100% independent as I'm sure you are still a part of the commonwealth).
Also Canada doesn't own the Caribbean so your argument is invalid. Making arguments based on dreams is stupid.
At least do what I do and come up with possibilities in the realm of realism (like Russia owning Alaska - that's a possibility).

But seriously, you can have those crap states - they're worthless and are really a thorn in our side.

Also, we have other non-state territories as well. Guam, the US Virgin Islands (ironically in the Caribbean), Puerto Rico, to name a few.
And there are others inhabited just by the US military as well and quite a number that are uninhabited.

How this argument has anything to do with the end of the world, well, I don't really care.
But really, if there was another World War then we wouldn't attack Canada (though we could, as technically we were told to not get involved with Europe - unless in our best interest - but nothing was ever said about Canada) as it wouldn't be in our best interest - hell, you'd all be bitching about the war anyway if we were to invade then you'd be bitching about that (even if it was just to set up a base of operations - which is something typical of allies, ya know). So either way, no matter what we do - you'll always bitch about it.
Honestly it would save us much trouble if we nuked you all now... but you were right in saying that would sit well with other countries.

So really, it's not in our best interest to invade Canada, it would be a pointless time waster.
No, if we were gonna invade another country then it should at least be one worth while that we could gain control of which would just make it easier for us in the long run.

Besides, most of us hate Canada in the same way most Canadians hate us so it wouldn't do any good for us to invade there.

Now if Canada somehow managed to become a Superpower overnight... THEN you would totally be worth invading.


Oh but really we have no reason to invade anyone as we seriously just don't have the need to.


But back on topic, I highly doubt a nuclear war will happen. Well, no, it could happen - oh those damn traitors selling our technology to the Soviets (yeah, the only reason they got it was because two American Communists sold it to them).
So it is a possibility, I just can't believe anyone would be stupid enough to try it.
Obviously if one gets attacked then you should also attack with the same or stronger force. Which would result in a war like that but I doubt anyone really wants to risk getting blown off the map like that. And if they do then they are stupid.
Anyone who values the lives of their countrymen wouldn't dare attack someone with that technology first.

A solar flare is the most likely fucking thing. One strong solar flare would wipe out communication on earth and destroy electronic items. Causing choas.
