Will the new intensified sanctions stop Iran from fulfilling their doomsday dreams?

I don't think so and neither do millions of others.  I am very much against war and senseless killing, even if it meant millions of muzzies might go to fornicate with their neverending supply of 72 virgins which would be a good thing for us infidels, BUT, in the case of Iran's threat of a nuclear war, the only solution is to take the bold step of a concentrated missile attack(s) on any and all sites known or suspected of nuclear weapons proliferation.

Two writers at RightSideNews know that sanctions might hurt but they won't work to deter the Iranian regime from it's mad dash over the cliff:

A.Savyon says:
With  the looming intensification of Western sanctions against Iranian oil and Iran's central bank, which went into effect July 1, 2012 due to Iran's refusal to comply with the demands of the 5+1 to stop enriching uranium and due to the fact that the diplomatic track has reached a dead end and the positions of the sides are irreconcilable,[1] Tehran responded in two ways.
It took a dismissive and arrogant attitude towards the sanctions, stating, and convincing itself, that they would have little effect[2] and assessing publicly that the West does not want a military escalation.
At the same time, recognizing the magnitude of the sanctions' impact on it, it demonstrated its might with a controlled threat in the form of the "Great Prophet 7" missile exercise,[3] and issued conditional threats against Western interests in the Gulf, Western targets worldwide, and Israel.

The European Union’s embargo on Iranian oil went into effect on Sunday, July 1. Other countries cut back their imports. The regime admits it’s feeling the sting but is boisterously defiant. These sanctions are the toughest yet but they will only succeed in stopping Iran’s nuclear program if the regime’s very existence is threatened. The key question now is whether it is too late for sanctions to work..
The pain caused by these sanctions should not be dismissed. Estimates vary as to how much of the regime’s revenue comes from oil exports, with some saying its 50% and others putting it as high as 85%. No matter what the truth is, the Iranian economy was a shambles before these sanctions began. In 2010, the regime had to cut funding to Hezbollah by about 40% because of financial restraints. Plus, rising domestic consumption takes away from Iran’s oil exports more and more each year. Some studies forecast that Iran would have to cease all oil exports in order to accommodate its own oil needs by 2015........
