In the Declaration of Independence, Jefferson states:
"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.--That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, --That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness"
What happened in Libya was supported and opposed by Jefferson for several reasons. First of all, Gaddafi died after being captured, without a fair trial. Jefferson, in my opinion, would have wanted to see Gaddafi brought to trial instead of being tortured and killed. However, Jefferson would have been in favor of the ousting of Gaddafi. Gaddafi violated the natural rights of man and deserved a trial in order to be punished. Ultimately Jefferson would have been in favor of removing Gaddafi from power, but not for how it was done.
Is what happened in Libya possible in the United States? I think to a certain extent no. While it is possible for the government to be overthrown, it is also possible for the people to express their discontent and have laws changed before it even gets to the level of governmental abuse as seen in Libya. These checkpoints were established in order to prevent something like the Libyan Civil War from happening and are written in the Declaration of Independence and in our Constitution. Because of how our government works, a democracy with checks and balances that ensures the people rights are protected, and the principles our nation was founded on, I do not think a civil war like in Libya could take place again.
