The EU may be rapidly rearming, but there is no way it will be in a position to help fight off a Chinese invasion of Taiwan in 2027. They won't have the navy. They won't have the force projection capabilities. They won't have the ability to get past China to get assets to Taiwan.

I’m talking about a deal with TSMC to safeguard their production.

Although, between the EU, Japan and Korea there might be enough of an incentive for China to think twice even without the US involved.

There are two countries in the EU that operate nuclear submarines and aircraft carriers. More with conventional subs. Shutting down the sea lanes in that area would be relatively easy for any number of European countries.

One thing that Ukraine (if Iraq and Afghanistan didn’t already) has proven is that it is much harder to win a war for a major power than the posturing would have you believe.
