On many levels i have an opinion on this:
1-after the Leftist turds attacked the US, then begged us to intervene in Darfur, and now this, I am of mind to tell the Leftist assholes: "**** you" after the pounding Bush and Conservatives took since 2003, for in essence, what would be doing to Khadafi exactly what was done to Saddam.
2-as a humanitarian, seeing armed animals defending Khadafi the dictator as they slaughter civilians does not sit well with me
3-if we allow Khadafi to survive in power against this rebellion, he will be VERY angry at the West, and might unleash levels of terrorism against Europe and the US on a level we have not yet seen before
Bottom line, even though the Leftist trash can choke to death after their endless screeching over the "illegal war on iraq," the hornet's nest of terrorism that Libya would become if Khadafi retained power would be untenable; he would seek massive revenge against the West for its support of the rebels, and would come after the US/EU like a woman scorned.
That I cannot accept, so at this point, we in the West have no choice, since we've openly sided with the rebels - we HAVE to depose him, and soon.
