This should be a reminder that the U.S. cares nothing for human rights violations and whenever it voices such complaints it does so for other selfish Geopolitical reasons that are maybe not revealed. This goes for any of the other Geopolitical powers as well. Let's not be useful idiots.
A better way to look at this is to recognize that geopolitics involve a multitude of political, economic, cultural, etc aspects. It's not that the US cares nothing for human rights violations, it's that we often prioritize different aspects. Caring does not imply a specific action.
Absolutely not trying to justify the relationship between the US and UAE. However, a maximalist position rarely leads to a positive change when so many parties and interests are involved.
The US is not monolitic. People who characterize it thusly do so do not capture the intentional-by-design unstable nature of the system. It remains, nonetheless, up to to 'us' to be not useful idiots.
