Senator Lieberman has called for the US to seriously consider air strikes against Iran because of the refusal on the part of the Iranian government to cooperate with the international community and cease all uranium enrichment. As a result, he has been dismissed by the mainstream media as a psycho, hell-bent on waging war all across the Middle East. Rather than having a serious discussion about how important/essential it might be to strike the Iranian regime, it is taboo to even raise such an issue and thus no serious consideration is even possible.
We all accepted Bill Clinton at his word that it was absolutely necessary to strike against Saddam's WMD facilities the day impeachment proceedings began against him in the House of Representatives. In fact, anyone who dismissed the president's decision as a diversionary tactic was accused by the Democrats and mainstream media as failing to take national security seriously. Yet any discussion of striking Iran, a country that is developing nuclear weapons openly and without shame, is considered crazy.
Now Senator Lieberman has gone off the deep end by suggesting that we should institute a similar closed-circuit television (CCTV) system as the one used in London to track the perpetrators of the recent terror attacks in our own large cities here in America. "Oh my goodness, how dare he suggest something so Orwellian!", is the typical response we should expect from the mainstream media and Democratic presidential candidates. Only the Republicans, at least at the national level, are willing to discuss such measures seriously and Lieberman would do himself and the country a huge favor by switching parties officially.
