1. Effort expended, money in particular.
2. Risk tolerance, toward exposure and blowback.
3. Competence of execution.
#3 is a function of the spy org, #1 and #2 are functions of pairwise relations between the particular governments.
Even the closest of allies spy on each other. We don't hear about it much, because risk tolerance #2 in such efforts is more wisely kept very low.
