Should I remind you of the prophet Mohammad 's PBUH courage or Ali's, and what about Khalid Ibn al Walid, have you heard about them? They were actually the ones who have inspired leaders like Salahuddin Al Ayyubi.
Do not fool yourself too much, its beyond ignorance.
The Arabs also fought -most of the time- much bigger armies than theirs and won in most cases. Should one remind you that by fighting Usrael , The Arabs were taking on the UK and France and then the US itself in 1973. They are your brothers who have brought you Islam with much sacrifices and with the utmost courage beyond your imagination.
I do agree with you to a certain pint, they might be fighting for their interest which includes the Yemeni one, since these lengthily Yemeni internal conflicts are more damaging to Yemen than to SA.
I agree with Pakistan for not intervening directly, although it would have been a nicer move if Pakistan would have sent a symbolic force -needed or not- to be stationed in KSA and to state that its troops will only intervene in case of a threat against Saudi soil.
Never, That was Arab Islamic democracy at its best, Turks went from Mamlouks (loosely translated to slaves) to rulers!!!
Oussama Bin Laden was a war hero in Afghanistan, who's Arab battalions Showed the utmost courage and sacrifice for their brothers in Afghanistan only matched by the most elite crack troops of Pakistan...
