We first have to defeat Russia, China, etc. Become independent of them and even defeat them before we start trying to peel off dependency on the US.
US is an ally, and in the near future we have to rely on them. That's it.
The US is a merciless imperial power.
We are all looking pretty nervously at the possibility of Trump's return. He'd be definitely willing to throw us under the Putin bus for a couple million USD laundered through his golf club or hotel bookings.
And you wouldn't actually revolt and do anything about that. So, on a whole, not really allies. Just other people who individually may or may not be our friends.
(Arguably, Trump, Xi and even Putin still have "potential" left.)
Not true, ridiculous statement.
But in the role of US president he would be able to do equal harm, just by acting like a 5 year old.
