Geopolitics

Conclusions that can be drawn from the Israel-Iran conflict and the broader global situation:
- Currently, international law only functions effectively in times of low tension. When crises escalate, countries tend to rely on power politics. Each state acts based on its own interpretation of national interest.
This will remain the case until the key destabilizing factors are eliminated.
- Russia is the main threat to the free world.
- Global instability will continue to rise until an effective system of international law is established.
However, as mentioned, achieving this will be difficult without first addressing the sources of destabilization.
- The global arms race is set to intensify, with more countries expanding their military capabilities.
- Once again, Russia has shown itself to be an unreliable partner. Alliances with Russia offer no genuine security guarantees.
- Iran’s air defense systems, including those supplied by Russia, proved to be ineffective.

I think the conclusions that can be drawn here are much narrower, as they apply to a case where a local regional power (Iran) has the explicit political goal of destroying another state (Israel). That is a nearly unique situation. I don't think any kind of international law could help.
