So the US has been paying Mubarak billions of U.S. tax dollars per year, while "encouraging" him to be a bit less autocratic and "listen" to his people.
This has resulted in years of Mubarak controlling Egypt through the use of secret police, torture, repression and censorship.
Now there is a reaction (that the West is actually taking notice of) the spin is what? That the Islamists are behind it all?
Well, if anyone was paying attention then they'd realise this whole protest movement started off with the students and the call from the 'Muslim Brotherhood' to take to the streets was hardly decisive in inflating the, already quite sizeable, numbers on the streets.
Nevertheless, there's money tied up in Mubarak so he'll probably cling on to power for as long as the powers that be identify a successor to bleed the country dry on their behalf.
