The existence of nukes takes direct military intervention off the table, full stop. Diplomacy is the only way unless a nuclear exchange is acceptable to you.
The US is so privileged that they don’t realize that “just sit back and let it happen” is how the rest of the world has had to deal with them for the last 80 years, and now it’s unconscionable to think they have to ‘let it happen’ with a foreign adversary themselves
I think the world would be better if every country had nukes and countries like Russia, Israel, and the US couldn’t simply steamroll every other country standing in their way.
