I agree. That was my first thought. The relative economic and military strength of Iran in the world today is, thankfully, not comparable to Germany in the thirties. They could be quickly crushed like an ugly mosquito were it not for their deeply cynical superpower enablers.
Iran is just an insect in the grand scheme. A dangerous bug in the mix, but still just an insect.
Putting enough pressure on Islam to force it to reform in order to survive is the most important part of the strategy on the war on terror. If Islam does not reform, they risk provoking Christians into taking off the blinders that have kept 99% of the world's Muslims safe from our ability to wage total war.
The WoT, to this point, has been a limited action, not by any inherent limitations of our own abilities, but by our moral and ethical limitations that take the extreme methods of genocide and pogroms off the table. However, if the Muslims push us too far, if they actually do try for a general apocalypse, or use WMDs - there is no way Islam will survive as a world religion. As a species, we may experience guilt in the future, but species survival is a very strong instinct, and righteous anger is a very real emotion.
There's also the fact that in a free society, Christianity emerges as the clear winner in a competition between the faiths. Very few people need to subscribe to a death cult to find meaning, but most people do have an overwhelming need for love and compassion. If Islam were a true faith, it wouldn't be so worried about competition in its scriptures.
Christianity requires that people make the conscious and free choice for salvation in Christ. This can neither be forced or coerced onto a soul. One does not send someone else to Heaven. Thus, freedom and Christianity are kin. True, Christians haven't always seen it this way, but I think it is how Christ intended his Word to be interpreted. I believe that as much as the Bible was inspired by God, that our country's founding Fathers were also similarly inspired to establish a system that provided the necessary freedom for souls to seek out salvation. And the fact that most of our country remains Christian, while Europe has become Godless is a testament to that achievement.
