Virtue signaling. The Krauts have to give the appearance of supporting the US and NATO but the fact of the matter is that they are dependent on Russia for a good share of their natural gas supply. They really, really need the Nordstream 2. And of course the Russians know this too. The Krauts will posture but come December Nordstream 2 will be fully operational.
When the weather gets colder in Germany the Krauts will quickly reconsider. This is all for show right now.
