War has it's own logic, even in an undeclared one such as the one between Israel and Iran. If surgical removals of Iranian assets, including human ones like the Iranian scientists, means that an Israeli or American city isn't someday destroyed by an Iranian atomic weapon then selective assassinations today are by far the lesser of two evils.
Don't assume that "scientist=educated=peaceful" is the operating equation here. There's no real reason to assume that the Iranian scientists are only building atomic weapons for Mahmoud because they're under duress. Saddam's WMD scientists were usually members of the Baath Party and were quite dedicated as individuals towards the concept of of a supreme Baathist Iraq dominating the entire region. Most likely the Iranian nuclear program people are as equally dedicated in their own right to the idea of a supreme Iran doing the same thing that Saddam wanted for Iraq.
I find it interesting that the automatic assumption is that Iran will use the nukes, North Korea has them but hasn't launched one yet and I am pretty sure Iran is more sane by a fair bit. The other point is how strange it is that you seem to need a US stamp of approval to build an atomic weapon when the US has shown the least ability to seek a peaceful solution. All this did was show everyone how little Israel/America care for human life and that apparently it is better to kill one of the many shop workers instead of the shop manager.
Iran is one of the few countries in the region that can be reasoned with but it seems the entire world prefers to shoot first and ask questions later. If you continue to back an animal into a corner and then hurt it, don't be surprised when it finally bites you.
