Translation: Saudi Arabia is preparing to do something nasty to the USA and they are changing their principle arms supplier.
Wrong. The proper translation is that the US has told Saudi Arabia that they better clean up thier act and hold elections or the hardware spiggot will be closed tight!
Net effect is the same, they are looking for alternatives - and to some degree, they are probably pretending to look so as to worry the US.
I doubt GWB gives a rip.
No way, I seriously doubt they have anything planned. The Saudi's are way too dependent upon us to even think about it. They are probably preparing themselves in case we pass some legislation limiting our own arms sales to them.
Everyone in the world knows American weapons are the best. I'd translate this article like this: Saudi Arabia is running out of money.
