Thats a load of balony.
If one country has stood with Pakistan under all circumstances, natural calamities, floods and earthquakes, wars and sanctions, its Saudi Arabia.
Using the term 'Arabs' is like generalizing an entire region with dogmatic logic. Arabs are not one people, they are different, distinct and often at the odds.
When was the last time Saudis backstabbed us? - Never!
I have studied with the Saudis and have met dozens of them. I didn't find a SINGLE Saudi who was even SLIGHTLY anti Pakistan or was 'conspiring' to backstab us. That too in times when frankly no one even talks to Pakistanis easily.
You cant give sweeping statements about a people without knowing them. If as you say that Saudis are knoen for backstabbing, i can safely say that we Pakistanis too have a rather pathetic habbit of blaming our ills on others.
