Lol, as a person that has been employed in the generation side of the energy sector, we would be fricked. Only people with it would be factories and anything else necessary for war. Be too expensive for the average person. Our lives would be sent back in time. Say goodbye to smart phones and the internet. Everything would have to be sacrificed to keep the war machine going.

Well, that'd change things, but I figured it was a year to prepare and then they'd begin. Landing forces in Canada and Mexico would be an offensive action as well.

But the only way to truly stop it would be to invade Canada. I think the other countries would easily march through russia and enter North America through Alaska which, in my opinion, the US would concede. At that point all you are doing is moving the front lines into canada.

---

Still have to deal with US air defenses and air power in Alaska but I agree, Alaska would likely be lost. Still, it's one thing to actually invade Alaska. It's quite another to move that many people through that terrain.

And it'd be better to move the front lines to Canada and give more space to fall back. Canada and the Northwestern US outside of Washington and Oregon is sparsely populated and offers little strategic value other than land. I may be missing something.

Doubt we'd be able to shoot them all down or out of the water. With as many commercial airplanes and military airplanes as there are in the world, coupled with water craft, two armies of over a billion people could easily amass in canada and mexico.

---

No, of course we couldn't take down all of them. But we sure as shite could take out a substantial amount and I doubt they'd resolve themselves to an all out assault considering the staggering losses they'd incur to only land a portion of their forces.

It would not be an easy feat.

The oilfields of the Dakotas, but other than that, I agree until you start getting into the midwest.

Which, considering the circumstances, would likely be dealt with

Imagine the resources wasted just to get them here. Then you'd have to feed, water, house and train them. Not to mention sanitation. shite, they'd be circling the drain before it started. They'd be like locusts in Mexico and Canada.

Didnt even factor this in but absolutely. Mexico and Canada are hardly resource rich enough to feed the troops off the land. And I'd LOVE to see a sustainable supply line be set up.

The world would first have to devastate our naval force and then the air force once they got closer

With a year of advance notice the Nuclear tipped weapons could be converted to conventional warheads and target lists drawn to match.
The entire fleet of needed mothballed aircraft at Davis-Monthan could be brought back online.
The same for all Navy ships and merchant marine.
The National Guard would be Federalized and expanded.
Inactive reserve former officers and nco's brought back into their respective service.
Inactive training barracks on all training installations activated and millions of soldiers trained in essential MOS's 11B, 11F, 12B(21B)
Strategic petroleum reserve filled
Invasion plans for Mexico and Canada planned and moved into location to provide "Lebensraum". Bases on foreign soil reinforced and expanded readied to invade Germany, Italy, Japan, Korea, Britain
Parts reserves, food, essentials, and medical positioned.
Coast Guard taken from Commerce Dept to Dept of Defense.
Veteran combat troops repositioned, replenished and rested from current countries engaged.
Also probably pull troops from Korea and Japan and allow them as non sustainable economies to be isolated and strangled without force.
All undocumented aliens deported or given immunity and chance of citizenship if they have skills critical to war effort or serve in armed forced.
UN dismantled
The true preemptive strike would be to unnationalize foreign oil reserves or to pull technology equipment and personnel home and end all financial aid to all belligerents.

The unknown quantity being the will of the people to fight and the ability of the depleted industrial complex to produce for a sustained operation.
It would be interesting, if it's a sustained scenario over three years the World maybe has a chance.
Under it's all USA

Any boat the world can wrangle. Year to prepare, no worries getting there. The entire world besides us.

You're forgetting we know the date of the attack which means we would be sinking tons of ships prior to the world being able to build up armies on our borders

quote:

---

The number of forces that would be lined up at the Mexican and Canadian borders would be staggering

---

There are a total of 32 mil. Canadians. That's every man, woman and child. Detroit alone could kick all of their asses.

And who's going to arm the Mexicans? Obama? Of course, since we already have Mexicans in every major city, that might be a problem. We'd have to euthanize them all in the year lead-up. Sorry, vatos.

By the time it got to shootouts the US would be fricked.

we, as America, cannot adequately hold backwater, poor countries like Iraq and Afghanistan

I don't think our air force can adequately protect our mainland, shoot any forms of transportation of troops down entering canada and mexico AND go out and shoot down infrastructure in other countries.

---

you'd be surprised

if the entire world attacked us, the only thing stopping the bombing of strategic targets would be our supply of bombs of which to do so

The world's air force and navy would be defeated in less than 12 hours.

Other countries would be on the defensive without us even needing to put boots on the ground

A land invasion from Canada and mexico is laughable with our technology.
