“The pace of modernization that the PLA is going through is unprecedented. It’s far outpacing what we are doing...

We are the smallest and oldest that we’ve ever been. The Chinese, the PLA, is the largest and most modern that it has ever been.”

—USAF Brig. Gen. Douglas Wickert
“That is risk. That is uncertainty. And that’s why what we are doing here at Edwards Air Force Base is extremely important.”

Fascinating perspective on China from the Commander of the 412th Test Wing, which plans and conducts all flight and ground testing of next-gen aircraft.
This is the first time I’ve seen a senior U.S. military official publicly address the two new advanced airframes that China recently leaked online (what some are calling the J-36 & J-50).

To counter China’s anti-access, area-denial approach to keep the U.S. out of the Pacific in a crisis, Dep. SECDEF says: “we’re changing the game,” and in “classified war games these approaches are paying off.”

“We’ve focused on developing and fielding innovative operational concepts and force designs for how we use our capabilities, showing that we can continually shape and master the changing character of warfare.

From the 1990s on, the PRC carefully crafted its elaborate military modernization to counter two longstanding U.S. approaches to power projection.

One was aircraft carriers, as deployed during the 1996 Third Taiwan Strait Crisis. The other was our multi-month, time-phased force deployments that moved America’s military might from the continental U.S. into theater before an operation — like Desert Shield before Desert Storm and subsequent regional build-ups preceding later wars in Iraq and Afghanistan...

While there is much more work to do, it’s already manifesting in aspects that are quite different from the military that the PLA built itself to beat.”

Outgoing U.S. Dep. Secretary of Defense:

“We want the PRC leadership to wake up each day, consider the risks of aggression, and think to themselves, ‘today is not the day’ — and for them to think that today, and every day, between now and 2027, in 2035, 2049, and beyond.”

Top conflicts to watch in 2025: @CFR_org

“The possibility that the U.S. could find itself in wars with not one but two major, nuclear-armed powers simultaneously is very real. The stakes today... cannot be overstated.”

680 experts prioritized 30 global hot spots (thread) Image
“The level of armed conflict around the world has steadily grown in recent years, which in turn has increased the risk of costly U.S. military intervention. This is particularly the case in the Middle East, which continues to be wracked by deadly violence across multiple countries. This violence has clear potential to intensify and spread. The horrific war in Ukraine that by some estimates has already claimed a million casualties also shows no sign of abating. This conflict could likewise escalate in ways that threaten vital U.S. interests and necessitate much deeper and more costly involvement. While the situation in the Indo-Pacific region is comparatively peaceful, numerous flashpoints exist, not least across the Taiwan Strait and in the South China Sea, that could suddenly ignite and rapidly draw in the U.S.”
“There have never been so many contingencies rated as high likelihood/high impact events (five) since the PPS began in 2008. Put differently, the level of anxiety that survey respondents feel about the risk of violent conflict over the coming twelve months has never been greater. Of the thirty contingencies surveyed, twenty-eight are judged to be either highly or moderately likely to occur in the next twelve months. Eighteen of those, moreover, would have a high or moderate impact on U.S. interests.”Image
