>Whatever happens is up to the US internal politics and the culture of the US nation.
If only the US would live by that when looking at other countries. Sanctions, embargos, trade-restrictions, threats are used against other countries by the US, why should they be treated any different themselves?
Because US is hegemon and can essentially do as it pleases without immediate consequence. This is why Russia and China have been focusing on destabilizing the US and minor geopolitical moves to chip away as opposed to directly challenging US authority.
The US is powerful and can do that. Well, at least up to some extend but even then it turns to be ineffective but as we see with the recent developments.
because for the US, to sanction basically any country is a blip on their economy, but for any other country, indeed blocs of countries to reciprocate that means not only losing your second or third largest trade partners but also shutting you economy off for electronics, software, international financial services, etc
