I feel like we (or the US at least) is past the point of being able to have a common enemy. Covid should have been a rallying cry. It wasn’t. Putin’s war should have universal condemnation, it doesn’t. politics, especially in the US but also elsewhere, prevent us from seeing a common threat. It’s obviously also the case with climate change, even moreso.

Unless the enemy is wearing a turban and flies a plane into a building, I’m not sure what woild inspire a wartime-like effort in the US.

Seth Klein (brother of Naomi Klein) wrote a book about just this for those interested. Its called A Good War.
