According to a 2011 poll by Transatlantic Trends very few people in the EU, US, and Turkey would support military action against Iran.

The report starts with preamble by saying: “In a year of tumult and upheaval, with political revolutions in the Middle East and North Africa, natural catastrophes in Japan, economic turmoil in Europe and the United States, the killing of Osama bin Laden, and heated debates over NATO, Transatlantic Trends paints a picture of a complex relationship between the United States and Europe and how they respond to global challenges. Transatlantic Trends shows that people respond to complexity with nuance rather than simplification.”

One of its key findings was in regards to Iran and the support that US, EU, and Turkish citizens would provide their states for a military attack on Iran.

In Section Four (Transatlantic Security), the poll states: “Very few people in the EU (6%), the United States (13%), and Turkey (4%) preferred military action over other options.”
