What makes it challenging to implement and uphold sanctions within the global system?

Explanation

The primary difficulty in enforcing international sanctions lies in the absence of financial incentives for compliance. Without such motivation, states have little reason to adhere to the sanctions. Additionally, even when many countries support sanctions, the targeted state may be encouraged to oppose them. Economic pressure can also inadvertently harm third-party nations, and withdrawing from beneficial trade often backfires unless universally adopted.
