Here we go again eaf-f16.That's not entirely true. They participated in GW1.
Your completely wrong.
Yes Saudi did particpate in GW1 in response to Iraqi aggression against an ally in Kuwait and then Iraq moved onto Saudi territory at Al Khafji.
Saudi did not provoke an attack on anyone - it responded with its full military and diplomatic capability after being attacked and won.
I would expect the same response if Egypt were the case.
