I would like to remove all acronyms, even those that are written inconsistently. For instance, in the list below (`text`), some of the acronyms miss an opening or a closing bracket, thus I would like the remove those too. I am only able to remove those with both closing brackets.

How can I adapt my current re expression so that it does not only focus on upper case chars with 2 surrounding brackets?

```
import re

text = ['Spain (ES)', 'Netherlands (NL .', 'United States (USA.', 'Russia RU)']  

for string in text:
  cleaned_acronyms = re.sub(r'\([A-Z]*\)', '', string) #remove uppercase chars with ( ). 
  print(cleaned_acronyms)

#current output
>>> Spain 
>>> Netherlands (NL .
>>> United States (USA.
>>> Russia RU)

```

**Desired output:**

```
>>> Spain
>>> Netherlands
>>> United States
>>> Russia

```
