Just read Gideon Levy’s article ‘Let Obama not be a friend of Israel’ in Haaretz:

His main argument is that what Israel needs is a US president who encourages Israel to end the occupation, not bolster it, who remembers that Palestinians, not only African Americans, have human rights, who stops funding Israeli re-arming, who encourages talks with Syria, Hamas and Hezbollah.
Amen!!
