please read paragraph:

At the onset of all emergencies, WHO ensures that predictable levels of staff and
funds are made available to the WCO, even if it is later realized that less is required,
with full support from the Organization and without blame or regret. This policy affirms
that it is better to err on the side of over-resourcing the critical functions rather than
risk failure by under-resourcing.

I, moreover, searched in my corpus and found the following translations for (no-regrets):

no regrets strategy= استراتيجية تحوط
no regrets strategies = استراتيجيات لا ندامة عليها
“no regrets” approach= "نهج مؤاده "عدم الندم

I opted for سياسة لا ندامة عليها based on the explanation paragraph above
