Neo-cons are defined by a sharper "right" outlook than traditional conservatives, but more importantly, believe in a big bad US that crushes all enemies and solves problems with guns. Neo-cons like Rumsfeld and Wolfowitz live in a world where everything is black and white, everyone is good or bad, commies bad, capitalists good, etc. The run into the war on Iraq was an example of Neo-con policy. Screw the UN, screw international approval, we are the big bad US, we John Wayne, etc. Here is a small list of neo-con views.
Neoconservatives…
Want the US to be the world's unchallenged superpower
Share unwavering support for Israel
Support American unilateral action
Support preemptive strikes to remove perceived threats to US security
Promote the development of an American empire
Equate American power with the potential for world peace
Seek to democratize the Arab world
Push regime change in states deemed threats to the US or its allies
Neoconservative – A "neocon" is more inclined than other conservatives toward vigorous government in the service of the goals of traditional morality and pro-business policies. Tends to favor a very strong foreign policy of America as well.
In the press Neocon is usually used to describe people of the far right who believe that might = right, and who believe in an indirect imperialism and the philosophy of Teddy Roosevelt..."speak softly, and carry a big stick".
