Where were all thise brave fighters 2 months ago when Israel invaded Lebanon?
You see my friend, the answer is very simple. You open a map, take a look. After that you can see that the Rebels are pretty far away from Lebanon border but Assad who is next door and is bombed on daily basis , never fired a bullet towards Israel. No?
Then open a newspaper and read how Hezbollah promised not to sign the ceasfire with Israel without Hamas doing it likewise, yet they signed?
Than take a look at Tweeter and see how suddenly the whole range of profiles are up in arms about so called slaughter of Christians. Etc
Open then Qur'an and check Surah Al Maida " Oh Muslims don't seek the protection from Jews and Christians....
Then open some book of Al Hadith, you can see that Dajjal will come from Esfahan. Carry on and you will see the story that the reaction to that will come from Haleb and Damascus.
Etc
As I have said before I am not Islamist, though I am not a secularist either.
As I have said before, over 90% of Islamists do not know the Religion or they don't actually care.
The last Islamist was Sultan Abdul Hamid.
As you can see , your question or questions can simply be answered by yourself.
Why all this wondering?
