Israel's sanction preferences target the people of Iran with a blockade of oil out and refined products in. That is an act of war. The US preference is for something targeting those involved in weapons and keeping the prople of Iran under the government's thumb. The real difference is between sanctions that work and reviving the tanker war. I don't favor the Saddam-like Tanker war approach. When you make war, sometimes people make war back.
