Minimum of one. There is no unlimited supply of these missiles. Also, annual fabrication quantity is quite constrained. We should stop providing these missiles to Israel; they are needed elsewhere, such as in East Asia, etc. Israel, under its present regime/leadership has already become expendable. Their choice, and.. Not the world's choice. They dug their own hole. Let them be buried in it. Also, many Israeli citizens are fleeing Isreael. They are tired of constant war. Living in such a failed/rogue state is no way to live. Leave Israel to those over age 75, those dried up old men who will die soon, anyway. There is and will be no redemption for Israel after genocide. There is never forgiveness for such crimes, as should have been learned by all....following WW2 War Crimes.
