There is no way to cause Iran to forsake building nukes forever. If you know of how to do this, you should share it with Kerry and Obama in lieu of blathering on and on as usual.
It is actually quite easy and would involve ZERO ground troops.
The Plan:State to Iran "Cease all nuclear activities by Sept 1, 2015 or bombing begins".
On Sept 1 if Iran has not followed directions, then begin a 1 week bombardment of Iranian Army bases.
Next state the same to Iran with 2nd deadline Oct 1.
On Oct 1 if Iran has not cooperated begin massive bombardment of all Iranian military airfields.
Next state the same with a Nov 1 deadline.
If Iran has not complied begin a massive bombardment of Iranian Naval facilities.
New deadlines would continue until Iran complied or was reduced to rubble as far as military and infrastructure.
The end game would be totally up to the Iranians when or if bombing starts/ends.
The two options for the Iranian Regime:#1. Iran complies and drop all nuclear programs and nuclear aims.
#2. Iran's military and much infrastructure is bombed into rubble
which would greatly reduce their ability to export terror and revolution.
If they rebuild, they would immediately be bombed again.
Plus with a greatly reduced and bombed out military facilities on a grand scale
the regime would be much more likely to be overthrown without a strong
military to protect them.
Again this could all be done without ground troops.
