America vs the rest of the world. What would happen?

[Speaker to Animals]

Well, if you are talking about landing directly on our Atlantic and Pacific coastlines, sure.

Who would do that? The Chinese could just cross over into Alaska. So could the Russians.

Landing somewhere in Central America and moving northward towards our southern border isn't a bad plan either.

If America were pinned into CONUS, I would do both.

[Smitty-48]

And then Canada annexes you without a single shot fired.

Nah, we don't want to take responsibility for the dumpster fire, we just try to keep it contained, and we don't need anymore territory, we could probably make use of Hawaii as a winter resort, but other than that, just leave well enough alone, don't touch the tarbaby, lest you can't get unstuck from it after.

Annexing America as it is now, would be like annexing a giant South Vietnam.

I suppose they could troops by submarine, but how feasible is that for entire armies that need to be landed quickly?

I discounted the bolded part because I figured you'd get advance satellite warning of transport ships moving across the Pacific and Atlantic oceans.

I suppose they could troops by submarine, but how feasible is that for entire armies that need to be landed quickly?

Totally unfeasable, a submarine can deploy a small team of special ops divers to conduct beachhead recce, but an amphibious force requires massive sealift and logistics tail, only the Americans are capable of moving whole armies by amphibious landing.

Even if you took the worlds largest submarine, the Russian Akula, and pulled all the SLBM's out to make room, that would still only be able to transport about a hundred troops or so, with no logistics tail to support them.

That's not really practical. Russia and/or China would stage just off the coast of Alaska. They'd have to establish naval and air dominance there and then make the short cross, establishing a beachhead in Alaska.

The total distance crossed by sea is actually pretty small there and can possibly be defended by air power and even artillery and missiles.

Not saying it would be easy, but they are not crossing over the wide Atlantic or Pacific like you insinuated at all. That would be crazy.

[Smitty-48]

Even the Americans couldn't invade America by amphibious means, it's a military impossibility for all intents and purposes. To invade America, you would need more military sealift than all the worlds military sealift combined.

[Speaker to Animals]

What about establishing air dominance over the Bering Straight, followed by airborne troops landing in Nome to kick the Americans out and secure landing fields for larger air transports?

Again: not saying it's easy by any means. I am just trying to think of the least fucked way to do it.

Logistics, ol' bean, it's all about logistics, the supply lines to maintain an invasion force from Eurasia to the heart of North America? Realistically a logistical impossibility, and therefore a military impossibility, for all intents and purposes.

Even if you had the lift, that line of communication would be so long and so tenuous, you'd just be inviting encirclement and thus sending your forces on a giant suicide mission.

Even just a tiny fraction of the population acting as insurgents all along that line of communication, would be able to cut you off resulting in a Stalingrad effect.

The longer the line of communication, the more troops you have to use to secure it, your entire invasion force would be required just to protect the supply lines, with none left over to actually conduct offensive operations.

[Smitty-48]

Even at the zenith of American power projection which is the zenith of world power projection, the Americans had great difficulty projecting logistics in the the Central Highlands of Vietnam from the China Sea, and that's was only a hundred miles or so, and they had east west highways to use, now, just imagine trying to project power through Alaska, the Yukon and British Columbia, down into the CONUS? That makes Vietnam look like a golf course, and come winter, it's -50C in Alaska, so good luck with that.

Frankly, just taking and securing Alaska would be a military impossibility, for all the amphibious forces of the world combined, there ain't enough Marines on earth, to even take and hold Anchorage by force of arms, never mind Washington DC.

I wonder if our Alaskan natives are as dangerous as yours in Yukon. Those guys would be a terrible force to reckon with if they went insurgency.
