Abbas is a follower of one sect which is apposite of Hamas and true beliefs in Islam, so he is not good for Palestianians and there is no doubt in this. You can see Middle Eastern leaders in Arab countries all of them are dictators except Turkey. So, you can think how would be good for israel to have all Muslim and Arab contries with right elected leaders as you see Turkey!
