This article, when it states it has almost a year since this Chip 4 Alliance was put forth by the Americans, not much has happened.
Seems to me it is clear, that the others do not want to join, and that their strategy is to delay and dither, and hope the Americans forget all about it.
It is kind of funny, because China is watching them squirm. China will not tell anyone of their internal developments in IC, for that will make them squirm even more.
This reminds me of Carl von Clausewitz. He wrote that in warfare, the longer the attack is taking place, the weaker it is, such as the longer the offensive thrust into hostile territory, the longer it goes, the weaker it becomes.
This tech war, and this Chip 4 Alliance probably is the most recent attack. Yet, it has gone nowhere, for like a year almost. That is exactly what Clausewitz saw on the actual battlefield.
So this Chip 4 Alliance, even if it comes into fruition, will be weak sauce.
