Good idea in theory. Don't suspect it is going to happen.
Problem is our politicians have a single primary priority. Their next election. And taking actions as you describe are not in the best interest of their staying in office. Taking action against Iran (however prudent it may be) would have a good probabliltiy of getting messy. Our congress pricks hate messy.
It's very smart of them to do this. They hold the pieces in place so the threat is real, but they don't act upon those pieces to fully establish the threat, so the West cannot react to that threat. It's a wonderful case of shadowboxing, and they are doing pretty well for themselves. And, coincidently, it also helps the West.
Our main concern is that the Iranians actually make the weapons. As long as they do not, and they just maintain the peaceful purposes, everything is fine. And if we can start barking at them to not make the weapons, we don't have to bite them because they won't make those weapons.
So, in the end, they will get all the materials ready, and they will have scientists and weapon experts on standby, but they won't go past that point, because there is no need to go past that point.

The entire nuclear crisis in iran is a spectacle.
The only point of pursuing a nuclear weapon is to deter a nuclear attack from another nation.
It's either 'shucks we cant nukem' or 'shucks, who cares.'
I doubt this is just about deterring some non-existent nuclear threat to them.

Israel may have a high quality military and sophisticated intelligence agencies. But those who believe that the Israelies could just sweep in and take out the Iranian facilities may be a little deluded. This is bit bigger of an udertaking than Entebbe or the Iraq reactor. And Iran has already taken a number of defensive actions to mitigate the Israeli threat.
The Iranian nuclear situation is a complex/messy one. And don't suspect there are going to be any quick or easy answers.
I don't think it is time for a military action or time for an economic sanction because economic sanctions only hurt the general population not the leaders. The leaders will not be hurting ever. Instead what should happen is that the US waits and sees what Iran does with this enrichment.
IF they use it for energy it would sure make us look stupid for attacking them because not only did we not have a good reason to attack but now we are stuck in Iran, Iraq, Afghanistan what a cluster f*ck to be in. So all we can really do is wait and see.
