I find it strange to read "Ariel Sharon" and "Peace Process" in one sentence.
Sounds sort of naiv - sorry.
If he wouldn't be on "our" side, his title would be more like the biggest "criminal against humanity" in modern times. Although there might be a tough competition with Henry Kissinger, Suharto, Augusto Pinochet, Saddam Hussain... man this list could be very long...
I hope for his recovery, so that we can see him in an international court. Even the court in Israel found him responsible for the death of thousands of people.
On the other hand you might be right, there could be worse people in power, like Benyamin Nethanyau (?)...
I better stop here, this is not a political forum.
