A reasonable person can say international law is unevenly enforced. This does not mean it does not matter. Both positive (what exists) and normative (what is ethical) considerations matter.
Communicating well matters. The above style of exaggeration is unhelpful if one cares about making sense of the world. Try to predict what happens in the future without factoring in international agreements and laws. Predictions from such models will be inferior, relatively speaking, to a version that does include paying attention to law.
> There is no international law.
