The Iranian people(not the Islamic Regime which is despised by the vast majority of the people in Iran) tend to be very western friendly and tend to be much more secular than most populations in the region.

The Iranian people are well aware that the airstrikes are not at all indiscriminate but are targeting the Regime(there are plenty of videos coming out of Iran of people filming and cheering as airstrikes hit Regime targets), indiscriminate military action would be what the Islamic Regime did when they killed tens of thousands of civilian protesters by firing automatic weapons into crowds of people. The Iranian people understand what is happening.
