Iran creates international panic

[ZenGum]

That sums up what I think is the (main) flaw in UG's position.

Ridding the world of tyranny, totalitarianism, injustice, etc is indeed an excellent aim. Military force is simply not a viable way to achieve this.

To invade, defeat, occupy, rebuild, democratize, and return to local control tyrannous nations by military force is an enormous and difficult task. Ten years per country is a bare minimum. Look how badly strained our resources are trying to do it just in Iraq (task underway, outcome uncertain) and Afghanistan (task underway, outcome very dubious).

And when we move on to the next one, the ones we have just left may well go wobbly and need help again.

To do this for the whole world? Russia? China? All the democratic nations together do not have the resources to achieve it.

It just can't be done with guns. Now, schools, THAT is in with a chance. Why do parents send their sons to extremist madrassas? Because that is the only education available. A few thousand reasonably funded secular schools in Pakistan and Afghanistan would do more to defeat AQ than the equivalent resources of military force.
Mind you, those schools will need guarding. AQ aren't stupid, and they would understand the threat it would pose.
