Nah, it's all for show.
Look at the s**t show that happened with the Paris agreement, and you will find that you can't fully trust the US with anything. maybe, the only thing that you should trust is the US bipartisan support for Israel and the Golf states, and even then, you will find that these relations are shaky today.
and what about Asia? they are fully independent and can just trade between themselves.
I can't see my self saying bye bye to Singapore, HK, Vietnam, Malaysia, Indonesia..etc any time soon
