The problem Syrians is not a matter of trust but it is matter of relations with outside World ,Syrians when they agree to do something ,they stick with it , they stick to what they believe so much till the end
but regarding the relations with the U.S (mainly is the reason of this distrust )and Iseral .Syria was the bigest supporter to The ex:U.S.SR in the mid east ,the regime was a communist one more than that of Nasser in Egypt,it was a real communist country Moscow used to supply it with the latest of its weapons (I read once that the war of yom Kippor 1973 was a war between the american weapons and Russian weapons),not to mention that the Regime aloi Muslim (Minority)while theMajority are Sunni ,that why I don't believe any crab regarding Al-Qaida relations with the Regime in Syria
The U.S doesn't trust syria coz Syria was always on the wrong side from the american view
For Iseral ,well I tell you something Sadaat once said I made war for Peace ,and he was right,he returned his land by war and Peace ,but Al-assad did none ,his army was used for terrorizing his own people then he lost the golden opportunity to go with Saddat,Gollan Hights are no impossible to be returned whether by War or Peace
I guess after the Camp David 1977 ,there will be no real peace achievements coz it was built on strong Bases
You are right about the Egyptian Government, I guess they are playing a great role in this
