(Mubarak did not step down because the US and Israel do not want him to, he is their puppet; but if the protests continue he will have to. and he did).
What is becoming clear is that the US has armed many Muslim nations whose leaders are dictators who have used US made weapons against their neighbors and their own people. The people can longer accept their fates under their oppressive governments; they want change. They want to choose and elect their governments, they want their independence from Europe and the US, and they want jobs and equal justice.
Because the US may not like the choices the people make i.e. the Palestinians' choice of Hamas or the Lebanese choice of Hezbolah; it keeps backing dictators like the Mubaraks or the Abdullah Bin Abdul Aziz al-Saudr.
Who will fall next?
People once angry organize and eventually prevail, the lesson to the world is making leaders tremble, good because this will inevitably lead to real changes, to social changes. The message to all leaders is that revolutions can happen anywhere and world governments must take notice.
