Judging from the recent statements by G7, Borrell and Lagarde, it seems like Yellen's speech will be hawkish, probably more decouple from China BS.
America is getting desperate. They're losing allies and influence left and right, their vassals' economies are getting screwed by Ukraine war and China's competition. USD hegemony looks increasingly under threat.

What can they do? Invest in their education and infrastructure, fix their hypercapitalism, improve relations with the world? We all know that kind of stuff won't happen.

Instead, all they can do is a few symbolic moves to attack China's economy that screws themselves up even further while only delaying China for a couple years. I expect to see more of this kind of meaningless and aimless provocation from the US until they ultimately lose.

The world can see the future path very clearly. Everytime China speaks, it's cooperation and investment. Everytime the US speaks it's some random hypocritical criticism of some random country, stirring up racial or religious nonsense or new sanctions and economic attacks.

I just saw this and frankly I'm very surprised. Esp radar, why can't they leverage their semiconductor industries?
Because radar doesn't use silicon for the transceiver elements, they use compound semiconductor III-Vs like GaN, GaAs, etc due to their much higher carrier mobility which enables them to carry high frequency signals without overheating or high loss.

The compound semiconductor industry involves different wafer sizes, processes, chemicals, etc than silicon. Wafer fabrication itself is much more difficult than silicon.

Seems Korea kinda "neglect" research&development in material science, explain weakness in marine turbine too.
