If we were still the God fearing Judeo-Christian society that we were 60 years ago, the religious zealots would not have had the ammunition (no pun intended) that they've had for going after American culture, and I don't think we'd be in this state of hysteria.
Man oh man, where to begin....
1. If America was the same Judeo-Christian society of 60 years ago -- a society that rather eagerly segregated and denigrated certain Christians based on the color of their skin, and told half of the Judeo-Christians that they have no place in life outside the home -- we'd probably have far bigger problems than we do now.
2. Certain of our policies directly contributed to the rise of OBL/al-Qaeda, Saddam, and the current Iranian regime - namely the backing of Afghan mujahadeen (including Osama bin Laden) against the Soviet Union by the liberal Reagan Administration, the support of Iraq in its war against Iran during the 1980s by the liberal Reagan Administration, and the support of an anti-democratic, repressive, unpopular Shah of Iran by successive liberal presidential Administrations of both parties.
Put another way, we nurtured the crazies and armed them back in the day, and now act shocked that they've decided to turn on the hand that fed them in the first place.
3. The people of the societies you reference do desire some reform and change. Problem is, their national leaders don't want change, don't want to give their people a voice or vote to make a possibility of change, and are backed by the USA out of political and military expedience.
While the Global War on Terrorism requires a strong military response to fight terrorists where they are, the ONLY way to actually WIN this war is to engage the hearts and minds of Muslims around the world. And the only way to effectively do that is for America to be consistent in both word and deed - something that it has not done with respect to the Islamic World for any significant length of time in the last 50 years. In this regard, the type of scrutiny you suggest takes us backwards - in the eyes of the Islamic world, it would be proof positive that America's words are a falsehood that attempt to shadow a racialist animosity of Muslims.
We need effective security - no question about that. But America is innovative and prosperous enough to protect itself without running roughshod over liberties - or repeating its past mistakes of scapegoating an entire group of people - should the nation actually choose to marshal its collective wealth and brainpower instead of acting in reactionary cowardice and xenophobic malice.
I'm off the soapbox now...
