I am curious in knowing what this "warning" consisted of. What might the consequences be? Full-scale embargo? Scratch that, already implemented. Preemptive strikes against Gaza? Done that, to no avail. Selective assasinations against Hamas' leaders? Ongoing, but botched the last one. Full-scale invasion of Gaza? Precision - guided nuclear strike? Eventual annexation? All options surely on the table ....
