I hope they are deceiving the West. Iran is enriching only for technological purposes.
Iran is still going to cooperate with the IAEA.
And Iran won't build the bomb.
A NATO member kills your general, in basic rules, you get to develop nukes as a deterrent. Then if US attacks while you are trying to get the bomb, world opinion supports peaceful Iran. Good will is very important.
Now if you want to secretly develop the bomb, you don't invite the IAEA.
If you think nukes won't be used against you so long as you don't have nukes, think again. Israhell if they get attacked by Iran could use nukes in retaliation. It is already in crime in most European states to not worship Israhell, so the people could be rounded up for questioning Netanyahu nuking Iran. Better to have the threat to take out the entire US, the entire UK and France, and Brussels and wipe Israhell off the map where there is not anything but dust and sand - by getting 6.000 or more nukes and maneuvering ICBMs with MIRVs.
This is about whether there is going to be an Iran and Iranian people. left on earth. You get enough nukes where it would be insane for them to want to nuke you.
