@georgetakei every soldier partaking in this war, is committing war crimes, since this war of choice is illegal to begin with.

Any nation that assist US, in it's illegal war, is participant in that illegal aggression as is outlined in United Nations General Assembly Resolution 3314, adopted on December 14, 1974

Iran is well within it's international legal rights to defend itself from *all* of it's aggressors by striking them on their own soil.
