US greatly lacks that separation in between the executive branch and the judiciary for simple reasons:

1. Top tiers judges are nominated by the executive branch, there are no other way up there.

2. For a high tier judge in US, a promotion is effectively a political promotion

3. US law, as I know, has no provisions for disbarring a judge for bad judgement even if it is plainly going against the what is written in the code. Only gross miscarriage of justice (graft, proven act of conspiracy, and 3 or 4 violations of court procedures) allows for impeachment by congress

All of that makes appointing politically aligned judges too attractive for executive branch officials who want to extend their powers through them
