Hal Brands and Michael Beckley argue in Danger Zone that China is not an unstoppable rising power. It is a peaking one — strong enough to challenge the existing order, and losing confidence that time is on its side. That inversion is the whole book, and it turns a comfortable assumption inside out. Bad economic news out of Beijing is not automatically good news for anyone else. Six stories from the past month show why.

The weakness is real. About 70% of Chinese family savings are locked in property, prices are falling, and up to 100 million homes sit empty, while the population shrinks and ages and local governments carry hidden debt built on land sales. That is the peaking-power diagnosis in a single story: a growth model losing momentum, a workforce contracting, reform made harder by centralization. The counterintuitive part is what follows. Economic trouble does not reliably produce caution. A leadership that believes its strategic window is closing has less reason to wait, not more.

The capability is also real. Chinese open-source AI models are now cheaper and more powerful than American ones, and China trains far more AI researchers. Nothing in Danger Zone requires every Chinese advantage to decline at once. The danger is precisely the overlap — military and technological reach still improving on top of an economy that is slowing, indebted and aging, with the sense that foreign coalitions are hardening. A country that is gaining in one column and losing in the other is the most volatile kind.

Taiwan is where the two columns meet. China's military dwarfs Taiwan's, so Taiwan bet everything on cheap, spread-out weapons — missiles, mines, drones, civilian resistance — to make an invasion painfully costly, while running short on ammunition, rifles, fuel and medical supplies, with full reserve mobilization taking sixty to ninety days. That is Brands and Beckley's own prescription, half-built. Their argument is that denial has to be in place before the crisis: dispersed, survivable, deeply stocked. Buying impressive platforms does not substitute for ammunition and mobilization. Once a blockade starts, years of underpreparation cannot be corrected.

Interdependence has already become a weapon. China's counter-punch is huge: it could cut off rare earth exports again, which would cripple US chip, defense, and AI factory plans. Trade was supposed to make conflict unthinkable; instead each side found leverage in the other's dependence. But the book cuts both ways here, and this is the part hawks skip. Pressure designed to permanently cripple China confirms exactly what Beijing already suspects — that the window is closing and waiting is losing. Coercion without an exit is not deterrence. It is a deadline.

Which makes the American side of the ledger the uncomfortable one. The war is stretching the US thin across too many fronts — Ukraine, Gaza, Iran, and trade fights with China over critical minerals, with Patriot and THAAD stocks down sharply and three years or more to rebuild them. Naming China the principal challenge means nothing if the interceptors are spent elsewhere. And when the argument goes the other way — that American power is fading, and the country will either pull back its global reach or stumble into wars trying to hold on — Brands and Beckley would call that the opposite error, equally dangerous. Complacency assumes primacy continues by itself. Fatalism assumes it is already gone, and a country convinced of that overreacts or abandons allies while a disciplined coalition could still hold the balance without a war. Our other Reading entry, on Graham Allison, describes a rising power displacing a ruling one. This book describes a power that fears it has already crested. Both endings are war. Only one of them has a clock, and reports of Chinese weakness are what the clock sounds like.
