Huh? What did the current administration do to force Russia to invade a sovereign nation? How did this administration topple Assad? Laughable that you think it’s ISIS running the show. How did the current administration convince Hamas to launch a war against Israel? Gtfo with your “liberal Pearl clutching” lmao you’re a joke

The virulent anti-nationalists are, themselves, often a very pro-war faction.

If we crossed the Yalu River today, do you think we'd be alive tomorrow to talk about it? Nuclear deterrence, as part of the taboo, prevents any nation from violating the sovereignty of a nuclear power. The only exception I know of is the Yom Kippur War, and if there is ever a person who never received a well-earned Nobel Peace Prize, it's Golda Meir.

China has a no first strike policy for now, so yes. Doesn't mean we'd have a good time though.

That we know about.

Hong Kong was very different than Taiwan would be. Taiwan will be a bloodbath as an armed, diehard anti-communist population fights to the death. And if China just wants to blow it all to bits, what was the point? They want to dominate the country and its people, not own a smoldering ruin.

That notion didn't stop Russia from scorching Ukraine, can't see why it would stop China.

Not being connected by land, thus having to force a naval invasion, is a big deterrent.

Can you give an example? Honestly don’t know who this is supposed to be.

Who would be willing to take the risk to do road maintenance in a radiation zone? Hitting a pothole at 120 mph would be devastating.

Depends on the pothole, but for some, driving at a higher speed is actually better than lower speed (short and deep ones) - the wheels just don't have enough time to fall significantly.

I believe the wheels still fall the same amount (the springs are pushing them down) but the suspension works faster/more efficiently. Once the wheel either bottoms out in the pothole or hits the trailing edge, the spring sends the wheel up faster due to the energy from the impact. The shock is thus pushed up faster, and upon reaching its full contraction, settles back down into position to level the suspension on the road. The car ends up moving less in space and the suspension regains its position faster. If the car were moving slower, gravity, momentum and the inefficient suspension would end up moving the car itself more which has a larger impact on the ride.

Worse, they mention supervised traffic, so presumably at some point people standing outside next to speeding traffic and radiation. Also, how fast is "safe" when seemingly you'll regularly be encountering crashed cars from people who didn't make it?

What do you mean crashed cars from people who didn't make it? The sign is basically a "minimum speed 40 mph" sign routinely seen on the interstates but with a bit more teeth. The sides of highways aren't usually lined with crashed cars (except occasionally when winter gets feisty).

I understood it as "this level of radiation could kill you in hours, but this is the only way to a fallout shelter." Reading other posts made after mine I appear to be mistaken.

What a perfect invitation to get on one of my favorite soapboxes. Spoiler: I'm a big fan of Brock Yates. Speed limits are an imperfect tool for an important problem. They were generally much higher, or nonexistent, on US highways before the 1973 oil crisis [0]. They were intended to save fuel, but weren't very effective. Nowadays, most people discuss them as a safety tool. They aren't great for that, either. Speed di…

> Also worth considering is that, even if higher limits reduce the rate of accidents, accidents at higher speeds are almost universally more severe. Obviously this is true, and especially important at low speeds, but I wonder how much difference there is between 70 and 80 — I would have assumed they are both typically fatal

The energy is exponential. It takes 30% farther to stop going 80 than it does going 70.

One of my favorite trivia is the scenario that a car going 50 mph sees an obstruction in front and slams on its brakes and stops just in time just tapping it. A car next to him going 70 mph sees the same object, has faster reflexes, and hits his brakes at the exact same spot of the road. He slams into the object at 50 mph.

Just the difference between 70 and 80 is the energy of going almost 40 mph.

There have been wargames where it has been simulated with China using its entire commercial fishing fleet as the amphibious assault force. It wouldn't be easily stoppable.

Why and how would a fishing fleet be unstoppable? Why is that better than actual landing vehicles?

It's not better. But if China is willing to take enormous losses, then they can push a lot of troops across the Taiwan Strait in requisitioned civilian boats. Essentially the maritime equivalent of a human wave assault.

The current government is going to weaken Western alliances. China is going to take Taiwan. Japan and South Korea are going to rapidly develop nuclear weapons programs. North Korea will increase the range of its missiles to reliably hit the entire US. The entire Middle East is going to nuclearize, with Iran first and then Saudi Arabia (the Trump white house was trying to arrange this last term, I suppose they'll succ…

Unless its existence and defiance of China was a sore point. Then an uninhabited ruin might be appealing.
