Is China probing U.S. with flying bayonets of sorts?

It’s easy to let your imagination run wild when it comes to the unidentified flying objects now making frequent appearances over North America.

Maybe the Martians really are coming.

Alternatively, maybe the UFOs that were shot down over Alaska, Canada and Lake Huron emerged from somewhere in China, just like the large balloon that was shot down Feb. 4 off the South Carolina coast. There’s a lot we still don’t know, and the White House is being appropriately careful not to jump to conclusions. Maybe it’s the Russians or something altogether innocent. But let’s think through the implications of the Made in China hypothesis.

Why would Beijing do it? The likeliest answer comes in the form of an old Leninist maxim: “Probe with bayonets. If you find mush, push.”

Balloons (if that’s in fact what the mystery aircraft really are) may hardly seem threatening like bayonets. But balloons can scrape up photographic and other data that reconnaissance satellites cannot.

Balloons could also expose gaps in what the Pentagon calls “domain awareness.” They help an adversary find our blind spots, not just in terms of how we detect threats to national security but also in how we conceive of them.

The point is crucial

— and too easily forgotten. In October 2000, a billion-dollar American destroyer, the USS Cole, was nearly sunk at dock in the Yemeni Port of Aden by a small fiberglass boat carrying high explosives. Less than a year later, nearly 3,000 people were killed on 9/11, when 19 hijackers turned commercial airliners into giant cruise missiles.

Both cases are examples of effective low-tech aggression. More important, they are also case studies about how a lack of imagination cripples our own defenses. We tend to think that our adversaries might act against us the way we would act against them. But part of Chinese military doctrine is based on the idea of Sha Shou Jian, or the “assassin’s mace” — an inferior power using weapons that can surprise and defeat a superior one. In that perspective, balloons operating in near space fit the paradigm.

Then there’s the possibility that Beijing operates this way because it has gotten away with so much worse.

If sending surveillance balloons into U.S. airspace is nervy, what about setting up a network of illicit police stations across the world, including in New York, to surveil and sometimes intimidate Chinese nationals living abroad? Or how about hoovering up the personal information of as many as 22 million U.S. federal government employees, a Chinese hack that was exposed in 2015? Or pilfering information about the F-35, America’s most advanced jet fighter? And what about the Chinese-owned app TikTok, which President Joe Biden belatedly banned on all U.S. government devices?

Finally, there’s Beijing’s policy of the ambiguous but probably calculated insult. Chinese foreign policy supremo Yang Jiechi took the opportunity to lecture Secretary of State Antony Blinken at length at their first meeting in 2021. The balloon that overflew Montana and other states arrived just before Blinken was supposed to visit Beijing in an effort to patch up relations.

There’s a coda to the Leninist maxim about probing with bayonets. It concludes: “If you encounter steel, withdraw.” Beijing has found little steel as it has probed everywhere from the cyber domain to the South China Sea.
